SYSTEM AND METHOD FOR PERFORMING DEMODULATION OF TURBO-ENCODED SIGNAL VIA PILOT ASSISTED COHERENT DECODING

Japanese Patent JP2011050064

A

To provide a telecommunications receiver system for accurately decoding a received composite signal having a data signal component and a pilot signal component.

A receiver system includes a first circuit for receiving a composite signal and extracting a pilot signal and a data signal from the received composite signal. A second circuit calculates a log-likelihood ratio as a function of a channel estimate based on the pilot signal. A third circuit scales the log-likelihood ratio by a predetermined log-likelihood ratio scaling factor and provides an accurate log-likelihood value in response thereto. A fourth circuit decodes the received composite signal based on the accurate log-likelihood value and the data signal.
