WebDec 8, 2011 · As shown in the constellation diagram for 256 QAM, an SNR of 32 dB is sufficiently large to demodulate a 256 QAM signal without significant bit errors – and, hence, frame errors. By contrast, in an environment with a lower signal-to-noise ratio, a smearing in the constellation occurs, which is evident at an SNR of 27 dB or less. WebJul 25, 2012 · When the BPSK symbols are transmitted over an AWGN channel, the symbols appears smeared/distorted in the constellation depending on the SNR condition of the channel.

WebOct 7, 2007 · @mohit: For BER, one would want to assign bits to constellation points (typically using Gray mapping). Then based on the received constellation point, map this to bits and count the errors. Typically, if one assumes Gray mapping, Pb = Ps/k. Since each constellation carries k bits, then Es/No = k*Eb/No. You may refer to the posts @ http://www.dsplog.com/2007/10/07/symbol-error-rate-for-pam/
