ADAPTIVE MODULATION ANDRATE cryptography FOR WIMAX

Priya jakhar

Abstract


Future mobile communication needs a hundred Mbps rate, video and audio streaming, asymmetric, multiple access, adaptational modulation and code rate, dynamic packet arrangement, adaptational antenna and IPv6 
utilization facility to inforce lossless communication. we have a tendency to propose AN adaptational Modulation and Rate cryptography Wimax (AMRC-
WIMAX) technique may be a promising thanks to increase the info rate with reliable transmission over wireless channels. During this paper, we have a tendency to gift numerous digital modulation techniques admire BPSK, QPSK ANd M-ary PSK systems applied to a coded WIMAX system in an AWGN channel atmosphere. This methodology compares the Bit Error Rate Performance of varied code rates mistreat- ment WIMAX technique and at last select the most effective code rate to realize higher BER
performance. it's found that the planned methodology offers the optimum
performance compared to the standard WIMAX system utilized in fourth generation.
