Method and apparatus for parallel demodulation of high symbol rate data streams in a communications system

An apparatus comprising:

• at least one processor;
• and
• at least one memory including computer program code for one or more programs,
• the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,
• receive a data stream of a data transmission, the data stream corresponding to a plurality of data symbols;
• generate a plurality of intermediate data samples corresponding to each of the data symbols;
• generate one or more representative data samples, corresponding to each of the data symbols, based at least in part on timing control signals and the intermediate data samples for the respective data symbol;
• drop certain of the representative data samples corresponding to each of the data symbols based on drop control signals;
• generate error correction signals by determining phase errors corresponding to timing errors in processing the data samples, and filtering the phase errors;
• and
• adjust the timing control signals and the drop control signals based at least in part on the error correction signals.

An apparatus comprising:

• a receiver module configured to receive a data stream of a data transmission, the data stream corresponding to a plurality of data symbols;
• a sampler module configured to generate a plurality of intermediate data samples corresponding to each of the data symbols;
• a control module configured to generate timing control signals and drop control signals;
• an interpolator module configured to generate one or more representative data samples, corresponding to each of the data symbols, based at least in part on the timing control signals and the intermediate data samples for the respective data symbol;
• a sample dropper module configured to drop certain of the representative data samples corresponding to each of the data symbols based on the drop control signals;
• a filter configured to filter the representative data samples to provide one or more filtered data samples corresponding to each of the respective data symbols;
• a phase detector configured to determine phase information regarding the filtered data samples;
• and
• a loop filter configured to filter the phase information, and to generate filtered phase information signals, wherein the timing control signals and the drop control signals generated by the control module are based at least in part on the filtered phase information signals;
• and
• wherein the control module is further configured to adjust the timing control signals and the drop control signals based on the filtered phase signals.
