IPC: H04B7/01
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To correct orthogonal distortion by providing a variable phase shifter that shifts the phase of a carrier, a Q detection circuit that receives a digital input signal and a carrier outputted from the variable phase shifter and obtains a base band Q signal, and a Q axis control circuit that controls the gain of the Q detection circuit.

Thus, even on the occurrence of phase distortion, the distortion can be corrected and the correction is made complete in a short time because the configuration is simple.
