Abstracf-We present a linear complexity multiuser detector that employs a joint succesive interference cancellation (SIC) technique to achieve better performance than the standard SIC detector. The key feature of Joint Successive Interference Cancellation (JSIC) is that it considers two users jointly at each stage of successive decoding. For the two-user(More)
An approach to successive interference cancellation is presented that exploits the structure of the combined signal constellation in a multiuser system. The asymptotic conditional efficiency of a successive detector is defined, based on the conditional probability of error at high signal-to-noise ratio (SNR), as a quantitative measure for evaluating(More)
