    Abstract: PROBLEM TO BE SOLVED: To provide a telecommunications receiver system for accurately decoding a received composite signal having a data signal component and a pilot signal component.
    SOLUTION: 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.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for a quick retransmission of signals in a communication system.SOLUTION: A transmitting terminal, transmits transmission signals in a form of packets to a receiving terminal, if the packet was intended for the receiving terminal, and the receiving terminal demodulates the packet. The receiving terminal then computes a quality metric of the packet, and compares the computed quality metric with a quality metric contained in the packet. If the quality metrics match, the packet is forwarded for further processing. If the quality metrics fail to match, the receiving terminal sends a request for retransmission of the packet. The transmitting terminal determines which packet needs to be retransmitted based on the request for retransmission. If delivery of the packet in accordance with the aforementioned description fails, retransmission in accordance with conventional sequence-number-based schemes, e.g., radio link protocol, is attempted.
