Type: article
Abstract: Fading is a fundamental problem in wireless communication.However Space time block code scheme is suggested to overcome this problem.In the paper various combination of transmit and receive antenna was considered, a mathematical model was driven and applied using simulation.The relation between signal to noise ratio and bit error rate was plotted.From results it is noted that the receiver diversity better than transmitter diversity, but if both diversity is used that gives better results as shown in Multiple input Multiple Output (MIMO), also signal to noise ratio (SNR) and bit error rate (BER) with carrier frequency offset (CFO) and without carrier frequency offset was compared.
