#1 Design of wireless communicatiosn system (Simulation) using the different empirical models available. Here, this simualtion tried to achieve the performance of the system for different communication parameters, Signal Noise Ratio, Fading, Bandwith of the channel and also the signal. This system includes the following implementations as a part of complete system design, Encoders      – BCH Encoder (31,21) and (15,7) , Convolutional Encoder(2,1,3). Inter-leaver  - Block Inter-leaver Modulation Techniques – OFDM, BPSK Channel Modelling – Rayleigh Fading Channel, Binary Symmetric Channel. Noise Modelling – Additive White Gaussian Noise Equaliser – Frequency Equalizer (Adaptive LMS) Decoders – BCH Decoder, Viterbi- Decoder
