As we know with time there is the huge development in wireless communication and with the pace of time traffic congestion problem arise and also ISP is unable to provide good quality of service. In our research paper, we implemented simulation result CDMA, OFDM, and UWB for different band pass technique, for example, BPSK, QPSK, QAM, 16 QAM, 64QAM etc. We calculated Transmitter and receiver message of CDMA, OFDM, and UWB for BPSK QPSK, QAM 16, QAM, 64 and QAM 256 modulation technique. Bit Error Rate (BER) and Signal-to-Noise ratio (SNR) for BPSK QPSK, QAM 16, QAM, 64 and QAM 256 modulation technique. MSE Equalizer for BPSK QPSK, QAM 16, QAM, 64 and QAM 256 modulation technique. It is impossible without smart antenna 4 by 8 means 4 transmitter and 8 receivers. Earlier we use only single or dual antenna now we use the array of an antenna to provide much efficient and good quality of service or we can say MIMO (Multi-input Multi Output).
