ABSTRACT:
A diversity combiner includes a plurality of branch receiving sections each receiving a QPSK modulation signal and a vector combiner. Each of the branch receiving sections includes a level detector which detects a signal level from the QPSK modulation signal, a phase difference detector which detects a phase difference from the QPSK modulation signal in each bit interval, and a data transformer which transforms polar data consisting of the signal level and the phase difference into rectangular data consisting of two rectangular coordinate values. The rectangular data obtained by the each branch receiving sections is combined by the vector combiner to produce combined rectangular data which is in turn transformed to combined polar data.
