Channel Choose
A WiMAX simulation where you can define the number of OFDM symbols to simulate, type of channel (SUI 1-6 or AWGN Channel), lots of BW and four kind of cyclic prefix. You can choose 4 different modulation as you can choose on IEEE 802.16dThere is no Simulink. Everything is code.I simulate the IEEE...
