Optimization of transmitted pulse shape and receiver timing in digital system

Abstract From the Canadian patent

In digital transmission, the combination of transmitted pulse shape and receiver, sampling time that maximizes the magnitude of the channel, output pulse sample is determined. The transmitted, pulse shape is represented as a linear combination of, orthonormal functions. The coefficients that multiply each, of the functions are determined by measuring at the receiver, (200) and transmitting back to the transmitter (100) the, response of the channel to each independently transmitted, function at an approximation to the optimal sampling time. A pulse shape is formed using the calculated coefficients, and is transmitted to the receiver where the timing of, its maximum is determined which …
