In this paper, performance analysis for different combining technique for receiver diversity in a MIMO system is presented. A general framework for diversity combining techniques in cooperative ...

This chapter reviews a design of passband quadrature phase shift keying (QPSK) transmitter and receiver in Simulink. It then evaluates bit error rate (BER) curves by ...

Abstract: We demonstrate the first use of a Time Modulated Array (TMA) steer able phased array at 73 GHz with data symbol vector modulation applied directly by the TMA. The concept removes the need ...
