The terms C, provide the bits of a test codeword to determine if a valid codeword has been generated. Atthe test codeword is evaluated for validity. Another embodiment of a method Toshiba Satellite 1130-Z23 Agere WLAN iteratively decoding an LDPC codeword using a threshold having multiple values includes having the threshold take on only two values during the iteration process. A first value is set at the minimum of the updated reliabilities, Z11, for the Zn generated in the first iteration prior to making decision comparisons. A second value is set at zero for subsequent iterations.

Such an embodiment provides a 0. Embodiments for a multiple threshold scheme decode any LDPC code in every situation. However, for a predefined code and known channel properties, the thresholds can be selected Toshiba Satellite 1130-Z23 Agere WLAN precisely. In the various embodiments, the number of iterations may be taken to be log2 n, where n is codeword length.

This provides a maximum number of iterations to perform before terminating the iteration prior to reconstructing a valid codeword. Experiments show that threshold timing Toshiba Satellite 1130-Z23 Agere WLAN optimization provide enhanced BER gain, but finding the exact dependency of thresholds, code structure, and channel properties is application dependent. Various embodiments or combination of embodiments for apparatus and methods for decoding and encoding communication signals using a multiple-threshold scheme, as described herein, can be realized in hardware implementations, software implementations, and combinations of hardware and software implementations.

The computer-readable medium is not limited to any one type of medium. The computer- readable medium used will depend on the application using an embodiment of the Toshiba Satellite 1130-Z23 Agere WLAN thresholds scheme. In an embodiment, the memory may store parameters used to iteratively decode the received codeword. Though an embodiment of a method using a multi-valued threshold can be used with any LDPC code, the following is presented as a non-limiting example.

This example provides an embodiment of a decoding method using a multi-threshold decoder on a low-density parity check code based on Reed Solomon codes with two information symbols RS-LDPC code. Thresholds for iterations 1, 2, and 3 are set at the minimum of the updated bit reliabilities, Zn, computed in the first iteration. The thresholds Toshiba Satellite 1130-Z23 Agere WLAN iterations 4 and 5 are set at 0.

Thus, in this iteration the threshold is set at The updated bit reliabilities comparison bit reliabilitiesZn, for the second iteration are determined to b e: Iterations are not needed Toshiba Satellite 1130-Z23 Agere WLAN this example, and the iterations are terminated. Though a second value was selected and scheduled for use in iterations 4 and 5, it was not needed. This example of an implementation of an embodiment for a multiple threshold decoding scheme and is not intended as a limitation to the various embodiments of the present invention.

Various embodiments for decoding a received codeword using a multi-valued threshold can be applied to any low density parity check code. In such embodiments, as the weight of the parity check weight is decreased, the decoding quality is increased. These embodiments may be applied in a method providing small complexity to the decoding scheme. Various combinations for providing the multiple threshold values during the iteration process can be used depending on the allowable complexity desired for a given Toshiba Satellite 1130-Z23 Agere WLAN. Additional reduction in complexity is provided using embodiments of the multiple-threshold decoding method since these embodiments can operate in hardware implementations without floating point numbers, which eliminates complexity and expense. Embodiments for a multiple-threshold decoding scheme may be adapted to be used in any system operating with a communication channel.

In various embodiments, data is provided by decoding codewords received from a communication channel. Decoding schemes employed may use thresholds in the decoding process. Thresholds in an iterative decoding process may be viewed as criteria against which a comparison may be made to control subsequent activities in the process. An embodiment includes a decoder having a multi-threshold decision scheme.

By multi-threshold decision scheme, it is meant that a threshold value is changed to a computed value or a predefined value during one or more decoding iterations. In a multi-threshold decoder, the threshold may have different values during different iterative segments of the decoding process. Embodiments for decoding schemes and apparatus adapted to such schemes include application of a multi-threshold decoder using an adaptive threshold selection and a fixed threshold selection. In an embodiment, during the first Toshiba Satellite 1130-Z23 Agere WLAN a maximum threshold value by absolute value is used and in following iterations, a change of threshold is applied in which the threshold decreases.

Changing the threshold values allows the use of a high threshold value during the first iteration leading to an absence, or reduction, of error propagation. Thus, if the decoder corrects even a small number of errors, the decoding at following iterations becomes significantly easier. Use of an embodiment of the multi-threshold decoding scheme may lead to a decrease in the number Toshiba Satellite 1130-Z23 Agere WLAN iterations made during decoding.

In an adaptive threshold selection, a threshold may be computed during each decoder iteration or may be computed in the first Toshiba Satellite 1130-Z23 Agere WLAN iteration and then used in subsequent decoding iterations, hi an adaptive threshold approach, the decoder needs no additional information about the parameters of the communication channel, such as noise dispersion, in which the signal carrying the codeword propagates.
