A receiver comprising A/D converters (1-1 to 1-4) for converting received analog signals (I1, Q1, I2, Q2) into digital signals, a quantization error reducing signal generator (2) for generating quantization error reducing signals for random noises, adders (3-1 to 3-4) for adding converted digital signals to quantization error reducing signals, bit shift circuits (4-1 to 4-4) for reducing the number of bits of the added signals, low pass filters (5-1, 5-2) for removing quantization error reducing signals contained in the digital signals reduced in the number of bits, matched filters (6-1, 6-2), and a demodulator5 (7). |
