Title
Code division multiple access based on independent codes and turbo decoding
Abstract
We study a multiple access encoding/decoding algorithm based on iterative (turbo) decoding. The algorithm is suitable for both synchronous and asynchronous systems. The quasi-orthogonal pseudo-noise sequences of the DS-SSMA system are replaced by independent channel codes constructed by combining convolutional codes and random interleavers. The interference is rebuilt using soft output information. The results show that the iterative joint decoder is able to completely eliminate the co-channel interference. The performance of the multiple access system tends practically to that of a single user system.
