High-throughput high-performance TDMA through pseudo-orthogonal carrier interferometry pulse shaping

This letter provides a novel method for doubling throughput in time division multiple access (TDMA) systems. Specifically, with pseudo-orthogonal positioning of carrier interferometry pulse shapes, a TDMA system is designed to support twice as many real symbols in a slot, without increasing bandwidth or slot duration. With regard to performance, the doubling of throughput comes at the cost of only 1-2 dB performance degradations at probability of error of 10/sup -2/.
