AB  - The Future Wireless Communication requires 100 Mbits/s Data rate, streaming audio/video, asymmetric access/multiple access, Adaptive modulation and coding, dynamic packet arrangement, smart antenna adaptation andIPv6 facility to enhance error free communication. Various digital modulation techniques have been taken for simulation and bit error rate is calculated in both MC-CDMA System and OFDMA system. The continuous phase modulation techniques ensures large bandwidth, high data rate and error free data communication. The convolution coder is mainly chosen to facilitate the Wireless communication. The output from serial to parallel converter is inhibited to various Adaptive modulation schemes like M-ary PSK, M-ary QAM, M-ary CPM and M-ary MHPM systems. The modulated output is then fed to MC-CDMA System and OFDMA system in fast fading Rayleigh environment. The BER performance and SNR ratio are observed for both the MC-CDMA system and OFDMA System inhibiting various modulation schemes and the corresponding simulation result are plotted using Mat lab and Simulink software. The outputs of various modulation schemes are plotted for both OFDMA and MC-CDMA systems. It is found that MHPM is found to be the optimistic Adaptive modulation technique for future Wireless communication.
