ABSTRACT:
A diversity receiving apparatus separately weights reception signals of a plurality of reception systems using combining coefficients based on a respective amplitude component of each reception signal and combines the weighted reception signals. The diversity receiving apparatus extracts symbol sections in the combined reception signals, and generates a clock for detecting symbols. The diversity receiving apparatus includes a converting unit314for uniformly multiplying the combining coefficients if every combining coefficient is below a predetermined threshold and I component ROMs, Q component ROMs, an I component adder325and a Q component adder326that combine the reception signals using the multiplied combining coefficients.
