Abstract
This paper deals with a multiuser cancellation detection scheme for DS/CDMA satellite communication systems where the BPSK modulation technique is used in transmission. The proposed receiver, defined as one-shot detector, is intended to be used at the end of an up-link satellite channel and considered in a communication system characterized by lack of synchronism between the users and multipath fading satellite channel. One-shot receiver basic assumption is to divide the users into two different groups according to the received signals power level. The reliable ones are directly detected and cancelled from the whole received signal before making the decision on not reliable users bit sign, without any further processing delay. The proposed scheme performance is evaluated in BER terms by means of simulations, proving that the proposed one-shot satellite receiver exhibits very good behavior for uniform users power distribution and shows reasonable near-far resistance. Moreover, the small computational complexity allows us to suppose a real time implementation for the proposed receiver.
