Very low intermediate frequency (VLIF) receiver and method of controlling a VLIF receiver

摘要

A very-low intermediate frequency (VLIF) receiver and a method of controlling a VLIF receiver. The method comprises receiving a first signal, the first signal including one or both of an on-channel signal portion and an adjacent channel interferer (ACI) portion; determining that the first signal includes a portion having a strength that is above a threshold; in response to determining that the first signal includes a portion having a strength that is above the threshold, estimating one or more IQ imbalance parameters for at least a portion of the first signal; and compensating for an IQ imbalance in at least the portion of the first signal using the one or more IQ imbalance parameters.

1. A method of controlling a very low intermediate frequency (VLIF) receiver, the method comprising:
receiving a first signal, by the VLIF receiver, the first signal including one or both of an on-channel signal portion and an adjacent channel interferer (ACI) portion; determining that the first signal includes a portion having a strength that is above a threshold, the determination being made by comparing a received signal strength indicator (RSSI) of the first signal prior to VLIF translation, and a received signal strength indicator (RSSI) of the first signal subsequent to the VLIF translation; in response to the determining that the first signal includes a portion having a strength that is above the threshold, estimating one or more IQ imbalance parameters for at least a portion of the first signal; and compensating for an IQ imbalance in at least the portion of the first signal using the one or more IQ imbalance parameters.
