- W1998052114 abstract "Worldwide Interoperability for Microwave Access is an emerging global broadband wireless system based on IEEE 802.16 standards. This paper investigates several modulation techniques for IEEE 802.16d (fixed WIMAX) based OFDM system including BPSK, QPSK, 16QAM and 64QAM with different cyclic prefix are tested for SUI-1 and SUI-2 channel conditions with channel bandwidth of 1.75MHz. For poor channel conditions, QPSK with 0.25 cyclic prefix is best modulation technique with least BER and, for good channel conditions 16QAM or 64QAM can be used. The effective bandwidth of the transmitted signal in wireless MAN-OFDM is also analysed and it is fall in the range of 87.29 %to 90.45%." @default.
