In implementing the Torrieri technique for comparing codes on the basis of information bit-error probability, the MATLAB function chooses was used. Using this function for large values of n and k can give rise to numerical precision difficulties that result from the factorial function. In order to illustrate this problem, execute the MATLAB function nchoosek with n = 1000 and k = 500. Develop an alternative technique for calculating nchoosek that mitigates some of these problems. Using your technique develop a performance comparison for (511,385) and (1023,768) BCH codes. Assume FSK modulation with coherent demodulation.
