Abstract
Embodiments of a method and apparatus for decoding signals are disclosed. The method includes receiving modulated signals, generating bits representing the signals, and associated reliability of each bit. The method further includes executing a first stage of decoding the bits using a first component code, and simultaneously executing the first stage of decoding again using a second component code, and executing a second stage of decoding using the first component code. The first and second stages of decoding are used to generate the bit stream.
Claims6
A method of decoding signals to generate a received bit stream, comprising:
- receiving modulated signals;
- generating bits representing the signals, and associated reliability of each bit;
- operating a first stage of N series-connected decoder stages for decoding the bits, the first stage operating using a first of M component codes;
- and
- operating the N series-connected decoder stages simultaneously, each of the N series-connected decoder stages operating using a different one of M component codes, wherein each of the N series-connected decoder stages use all M component codes for each iteration of decoding, wherein M is at least as great as N, and wherein N is greater than two;
- and wherein
- the plurality of N stages of decoding are used to generate the bit stream.
