Abstract:
The present invention relates to a method of improving the performance in bandwidth constrained communication systems while reducing the complexity of the equalizer used for information retrieval, as well as to improving the capacity of communication systems. The said properties are achieved by appropriate information encoding, prior to signal shaping before transmission, whereas the equalizer complexity is reduced by applying the intersymbol interference shortening filter prior to the information retrieving equalization. A proper combination of the recounted elements is capable of providing a qualitatively improved and previously unsuspected performance, as compared to its constituent elements.

Claim (Index 10):
A method comprising:\n providing a plurality of waveforms in a transmitter, wherein the waveforms comprise information; appending the information comprised in the waveforms with error-control redundant symbols using code comprised in an error control encoder of the transmitter to form appended waveforms; shaping the appended waveforms using a pulse-shaping element of the transmitter that intentionally introduces memory onto the appended waveforms to form bandwidth-constrained waveforms; transmitting, by the transmitter, the bandwidth-constrained waveforms over a bandwidth-constrained channel; retrieving the information from the bandwidth-constrained waveforms using an information retrieving equalizer of a receiver; and decoding the code employed by the error control encoder of the transmitter using an error control decoder of the receiver; wherein: the error control encoder is designed in conjunction with the memory introduced into the waveforms at the pulse-shaping element; the error control encoder and the error control decoder are matched to the constrained bandwidth channel; the method is for use in digital communication systems conveying information symbols at a certain symbol rate in which the information bearing bandwidth-constrained waveforms are filtered to a bandwidth narrower than the communication symbol rate; and the memory introduced into the appended waveforms and the error control encoder achieve an improved system performance in information transmission compared with systems not employing the bandwidth constraint, not employing memory, and not having the error control encoder and the error control decoder matched to the bandwidth-constrained channel.
