Simulation of a plane wave impinging on a dielectric cylinder using FDTD

Considered a 16QAM communication system. The information rate is 2 Mb/s and the carrier frequency is 12 GHz. Assumed perfect synchronization. a) Simulated the system if the channel is AWGN and draw bit error rate of the system versus Eb/No. Compare the results with what you obtain in theory. b) Considered (15,11) Hamming code. Apply this code into the above system. Compare the results with what you obtain in theory. c) Simulated uncoded system if we have a Doppler Spread due to mobile movement in the channel. Simulate and draw the bit error rate of the system for maximum mobile speed 42.3 Km/Hour. No equalizer is used in the system. d) Applied coding of part (b) into the system of part (c). Simulate the system and discuss the results. e) Designed an interleaver for the system of part (d) to improve the coded performance results. Simulated the system.
