  • Abstract
    We show that the capacity of a Gaussian multiple access channel can be approached by interleaved low-rate codes together with a simple chip-by-chip iterative decoding strategy. Based on a rate ≈ 1/69 code and with a total of 35 simultaneous users (the aggregate rate ≈ 1/2), performance of BER=10-5 is observed at Eb/N0 ≈ 1.4 dB, which is close to the corresponding capacity limit (Eb/N0 ≈ 0 dB).
