Self-encoded spread spectrum (SESS) is a novel modulation technique that acquires its spreading sequence from the randomness of an input data stream rather than through the use of the traditional pseudo-random (PN) code generator. The statistical properties of random codes in SESS offer a number of advantages over the deterministic PN codes. In this paper we propose a multiple-input multiple-output...
A multiuser detection based on quantum particle swarm optimization (QPSO) with Pareto optimality is proposed for the space-time block coded-multicarrier code-division multiple-access (STBC-MC-CDMA) system. Due to the spatial diversity, the signals received at the different antennas are faded independently, resulting in an independent log-likelihood function (LLF) for each antenna. To resolve the multi-objective...
