Tufts (1965), Smith (1965), and Berger and Tufts (1967). “Faster than Nyquist” transmission has been studied by Mazo (1975) and Foschini (1984). Channel equalization for digital communications was developed by Lucky (1965, 1966), who focused on linear equalizers that were optimized using the peak distortion criterion. The mean-square-error criterion for optimization of the equalizer coefficient...

Doppler-Free Digital Communications

| The existence of doppler has always been an inconvenience for digital communications. Several schemes have been proposed to deal with the problem, often involving some kind of doppler tracking and/or compensation algorithm. All these schemes do, however, increase the complexity of the receiver. Furthermore, the need for exactness in the doppler tracking scheme adds an extra dimension to the s...

Digital Communications for Relay Protection

Electric utilities are expanding communications infrastructure due to increased need for information. Due to performance, price, and technological advances, digital communication systems are frequently chosen as this multiple user data network. This two-part paper describes the application of digital communication in power system protection. Part 1 describes the digital communications architect...
