explain the operation of matched filter receiver I we discussed in class, and from your background in Signal and Systems, 16. (10pts) A M-ary QAM system transmits 4.8Kbps with an error rate of less than 10^-6. The center frequency is 1 GHZ and the channel has a bandwidth of 4 KHz. The channel attenuates the signal by 10 dB. The noise in the channel can be modeled as AWGN with a power spectral density of 10^-7 (watts/Hz). Estimate the required transmit signal power, Pt cts) The modulation format is DAM
