Error Probability and Bandwidth of Digital Modulation

The bandwidth in which 99 percent of the power is contained is presented for ASK, QASK, OQASK, PSK, FSK, and MSK. An example is given in which the bandwidth of FSK is one eighth the bandwidth of ASK and of the modulating signal. Error probability is presented for the various types of modulation with various detectors, detector filters and Butterworth receiver filters of order
N = 4
or
\infty
. Comparisons are made between the performance and bandwidth efficiency of the various systems.
