QAM Tutorial2

This m-file calculates the theoretical exact(in AWGN) SER verses Eb/No for even number of bits per s

Description

Besides calculating the SER verses Eb/No for the various levels of QAM, The m-file shows the coding gain required to closely approach Shannon's channel capacity limit for 4QAM,16QAM,64QAM,256QAM and 1024QAM. Notes are given at the end of the m-file.
