Alternate Time-Switched Space-Time Block Coding Technique for Single Carrier Modulation

摘要

This paper proposes an alternate time-switched transmission technique for single carrier modulation system with frequency domain equalization. Additional maximal ratio combining diversity gain is obtained by adding a transmit antenna and a switch. Alternating transmit symbols result in zeros which make maximal ratio receive combining possible in the receiver. Simulation results show that it has better performance than the traditional algorithm at the expense of one additional antenna.
