Power penalty in bit error rate due to limited transmission bandwidth.
01 January 1987
Power penalties in bit error rate due to limited transmission bandwidth are studied theoretically and experimentally. For less than a 0.5 dB penalty, a transmission bandwidth of 1.25 times the bitrate is required. If there are n components contributing equally to the transmission bandwidth, each of these components should have a bandwidth 1.25 sqrt n times the bitrate.
