I simulated the SPACE TIME BLOCK CODED system based on Alamouti scheme, where the modulation is BPSK. Now I am trying to extend that to QPSK and higher modulations. Since for SISO channels, BER curve for BPSK and QPSK is equal in AWGN and fla

Research towards meeting the higher demands for higher data rates was the main reason for the birth of an evolution technology towards the 4th generation mobile communication systems. This evolution to the current 3rd generation UMTS systems
