In this homework assignment we consider QAM baseband transmission over a noisy channel with signal attenuation and phase osets.  A block of ( L + K ) symbols is transmitted at a symbol rate of R s = 1 =T symbols per second.  The symbols u j with j = 1 ; 2 ;:::;L + K are taken from some QAM constellation alphabet A .  The transmitted waveform is u ( t ) = L + K X j =1 u j p ( t
