Simulink Model Analysis of Modulation Technique of UWB, OFDM and CDMA for Different Parameter

With pace of time there is tremendous development in communication and on other hand as population increasing exponentially with time many severe traffic situations arises for example congestion problem, quality of service and cost also. A researcher always tries to resolve complexity of the system means system must be simple, cost effective and easy to use. In our dissertation research area is to compare different characteristics parameters of digital modulation technique so that a final conclusion can be made which technique is best one when we transmit data and finally it reach at destination with minimum bit error rate (BER). In base paper only CDMA technique is considered but in our dissertation work UWB and OFDM also considered. 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, Calculate Transmitter and receiver message of CDMA, OFDM and UWB, Bit Error Rate, Signal-to-Noise ratio (SNR) and MSE Equalizer. Besides this our dissertation having multi input multi output (MIMO) antenna concept used. Earlier single antenna concept was used, now we use array of antenna to provide much efficient and good quality of service or we can say MIMO (Multi input Multi Output).
