ABSTRACT:
A synchronization network that provides frame timing that is particularly suited for a Eureka-147 system is disclosed. The synchronization network reduces the typical amount of computations required to provide for frame timing schemes and includes matched filtering operations that separate the waveforms of null and sine symbols contained in the multiple carriers of the Eureka-147 system. The matched filtering technique are accomplished before a fast Fourier transform operation and which accomplishments elimination of the need of an inverse fast Fourier transform operation normally performed by one of the receiver elements of the Eureka-147 system. This elimination is accomplished without degrading the performance of the Eureka-147 system.
