NON-INTEGER OVERSAMPLED TIMING RECOVERY FOR HIGHER ORDER QUADRATURE MODULATION COMMUNICATION SYSTEMS USING QUADRATURE-PHASE SAMPLES

摘要

Apparatus and method for performing entirely digital timing recovery for high bandwidth radio frequency communications. The received digital data source can be sampled from any (minimum 2×) non-integer oversampled transmitted data. This method re-samples the data through interpolation and phase adjustment. The output phase error adjusts the receiver's Analog-to-digital Convertor sampling clock to improve synchronization with the transmitter's Digital-to-analog Convertor clock phase, thus improving transmitted symbol recovery.
