CHANNEL ENCODING WITH TWO TABLES CONTAINING TWO SUB-SYSTEMS OF A Z SYSTEM |
摘要 |
A channel encoding method of calculating, using a programmable processor, a code identical with a code obtained with a hardware channel encoder. The method comprises: - a first step (112, 120; 222) of reading the result of a first sub-system of parallel XOR operations between shifted bits in a first pre-computed lookup table at a memory address determined from the value of the inputted bits, the first pre-computed lookup table storing any possible result of the first sub-system at respective memory addresses, and - at least a step (116, 124; 226) of carrying out an XOR operation between the read result and the result of a second sub-system of parallel XOR operations using an XOR instruction of the programmable processor. |
