Abstract
Beamforming phase correction in a wireless communication circuit is provided. The wireless communication circuit is configured to emit multiple processed signals, which are generated by applying a codeword to a radio frequency (RF) signal. The codeword defines a set of complex-valued coefficients that will cause each of the processed signals to be associated with a respective one of multiple defined phases such that the processed signals can form an RF beam when emitted simultaneously from multiple antenna elements. However, some or all of the defined phases can be changed, for example, when the processed signals are amplified. In this regard, in embodiments disclosed herein, a phase correction circuit is configured to determine one or more phase correction terms and apply the determined phase correction terms to one or more of the processed signals to thereby correct undesired phase changes and restore coherency among the processed signals.
