... Rayleigh fading for each path. The systemparameters are Nt= M = 100 for all cases; for PAM-16, K =16, Nr= 13; for PAM-8, K = 6, Nr= 6; for PAM-4, K = 8with Nr= 9, and for PAM-2, K = ... (i) for higher-order modulations we group Bdata streams together which will form a 2B-ary PAM sym-bol. This is done as follows: the antenna sequence partitionssk,m for the data streams forming ...
