Abstract

In this research work, performance of different channel equalization techniques and various M-ary modulation schemes (MPSK, MQAM and DPSK) for DWT based MIMO Multi-Carrier Code Division Multiple Access (MC-CDMA) wireless communication system has been analyzed through simulation. We propose this system using convolutional coding scheme over AWGN and Rayleigh fading channel with implementation of Walsh Hadamard code as orthogonal spreading code. In this paper, we derive a generalized analytical framework to evaluate the Bit Error rate (BER) with respect to Signal-to Noise Ratio (SNR) and also use Electronic Codebook (ECB) mode as cryptographic algorithm to encrypt the actual data for security issues.
