METHOD FOR SUBRATE DETECTION IN BANDWIDTH CONSTRAINED COMMUNICATION SYSTEMS

摘要

The present invention relates to utilization of sampling rate at the receiver that is below the symbol rate of a bandwidth constrained communication system. Furthermore, if the appropriate up-sampling technique is used, the method avails full retrieval of the information from the under sampled received signal.

主权项

1. A method for communication receiver design that relies on a sampling rate that is lower than the transmitted symbol rate comprising the following steps:
(a) undersampling with respect to the transmitted symbol rate, performed by a receiver in receiving information; (b) performing up-sampling of the received information at a receiver, employing interpolation relying on digital signal processing, up to at least the symbol rate; and (c) passing the up-sampled information to remaining elements of a communication system detection chain in the receiver.
