There have been solid theory foundation and mature methods to analyse the ordinary communication system which is disturbed by additive white Gaussian noise.

Based on Stuber G.

The relationship between symbol error probability and bit energy-to-noise ratio (SNR) are given for RS codes,dual-k convolution codes, and repetition codes. The results indicate:it is not quite obvious for the improvement of system performance if we merely increases number L of diversity, only whenwe adopt both diversity and code technique at the same time, we are able to improve the system performance efficiently.
