An Improved Quasi- Orthogonal Space-Time Block Codes for Diversity Reception in Wireless Communication


Quasi orthogonal space time block codes have been proposed to achieve higher symbol transmission rates for more than 2 transmit antennas at the expense of losing the diversity gain. In this paper we propose a method to improve its transmit diversity with one bit feedback. This method useful for extend any space-time code constructed for 4 transmit antennas… (More)
