Method and apparatus for generating a correction term

摘要

A method and apparatus for generating a correction term is disclosed. A plurality of data packets are received from a transmitter. An acknowledgement (ACK) signal is generated for each data packet in which an error does not exist, and a negative-acknowledgement (NACK) signal is generated for each data packet in which an error exists. The generated signals are mapped into a binary signal. The binary signal is filtered to generate a filtered binary signal. A target packet error rate (PER) is generated. An error signal is generated by subtracting the target PER from the filtered binary signal. The error signal is processed to generate at least one correction term. The at least one correction term may be used to bias a signal-to-interference ratio (SIR) estimate of a communication channel established between the transmitter and a receiver based on the received data packets.
