Title: Direct detection receiver
Inventor: SASAKI KAZUTOSHI
IPC: H03D1/22
Filed: 1991-12-11
Abstract: PURPOSE:To correct a level difference between two orthogonal conversion signals with excellent response and stability. CONSTITUTION:When gain control amplifiers 61, 62 correct a level difference between two signals I, Q resulting from applying orthogonal transformation to a reception signal with reference signals whose phase differs by 90 deg. and a voltage Ei obtained corresponding to a level difference of the both is at the outside of a range W1, a level control circuit 80 gives a predetermined current I or -I to a gain control amplifier 61 as a correction AGC voltage and the circuit 80 stops the voltage when the voltage is within the range W1. Thus, level correction with respect to a reception electric field strength change by an AGC voltage based on a demodulated voice signal and correction of a level difference by the level control circuit 80 for the response and the stability are both implemented. Furthermore, the signals I, Q after the correction are corrected with high accuracy by the digital signal processing by a correction circuit 65 to suppress distortion in the demodulated voice signal.
