Abstract :
Presents a technique that can be used to partially recover the transmitted signal from a received signal that is composed of time delayed versions of the transmitted signal. The recovered signal is expressed analytically in the frequency domain. An approximation for the extracted signal in the time domain is also obtained. Here, the frequency representation of the transmitted signal is restricted to a specific class of functions, namely minimum phase functions. Except in a few cases, the extracted signal is distorted in comparison to the transmitted signal. Consequently, these analytic expressions can be used to determine how the time delays and the form of the transmitted signal affect the amount of distortion observed
