Abstract
A wireless multiple access method allows multiple transmitters to access the same channels so that substantial interference occurs. The transmitters use low rate turbo coding and the receiver uses multi-user detection to separate and decode the transmissions. Different propagation and/or transmission characteristics between the transmitters help to distinguish the transmissions at the receiver. The transmitters may add random variation to their transmission timing, power and/or frequency to assist with decoding.
