Abstract
The present invention provides a method and circuit for equalizing and compensating IQ imbalance at the same time. The method includes: down-converting an RF signal to generate a baseband signal, and driving an adaptive equalizer to process the baseband signal for achieving equalization and IQ imbalance compensation simultaneously.
Claims19
A method for equalizing a signal, comprising:
- down-converting an RF signal to generate a baseband signal;
- and
- utilizing an adaptive equalizer to process the baseband signal such that the baseband signal is equalized and an IQ imbalance of the baseband signal is compensated simultaneously.
A circuit for equalizing and compensating IQ imbalance simultaneously, comprising:
- a down converter for down-converting an RF signal to generate a baseband signal;
- and
- an adaptive equalizer coupled to the down converter for receiving the baseband signal and processing the baseband signal such that the baseband signal is equalized and an IQ imbalance of the baseband signal is compensated simultaneously.
A method for equalizing a signal, comprising:
- down-converting an RF signal to generate a baseband signal;
- generating a plurality of equalization coefficients, wherein the equalization coefficients correspond to channel response and IQ imbalance;
- and
- processing the baseband signal according to the equalization coefficients to equalize the baseband signal and compensate an IQ imbalance of the baseband signal.
