The ATSC broadcast television system used in the US transmits video signals at an
average rate of 18.34 Mbps and employs 8-VSB modulation. QPSK modulation would allow receivers to achieve the same BER as 8-VSB at a lower CNR, increasing the range of the broadcast transmitters. Why isn't QPSK used in the ATSC system?
