In this paper, the authors first build up a wireless communication simulator including gray coding, modulation, different channel models (AWGN, flat fading and frequency selective fading channels), channel estimation, adaptive equalization, and demodulation. Next, they test the effect of different channel models to the data and image in receiver with constellation and BER (Bit Error Rate) plots under QPSK modulation. The transmission of JPEG2000 images using an Unequal Power Allocation (UPA) scheme and Orthogonal Frequency Division Multiplexing (OFDM) technique over different channel models is presented.
