Synchronous space hopping on hybrid frequency-time division duplex: a new multiple access technique proposed for beyond 3G evolution

In this paper the synchronous space hopping based on time reuse and hybrid frequency-time division duplex is proposed. This technique provides intra and inters cells isolation for time slotted scheduling based systems, where resources are shared among the users by means of a scheduling. It´s aimed at a high and distributed data rates resulting from a high signal to interference and noise ratio (SINR). In CDMA platform it constitutes a new multiple access technique, which is examined on its downlink and compared to the conventional CDMA. The results are presented in terms of coverage, throughput and latency from system level simulations. A significantly increase in SINR of up to 15 dB, which corresponds to a better coverage, a higher sector throughput and a lower of equal user number based latency compared to the conventional CDMA.
