Title:
MOBILE RADIO RECEIVER
Document Type and Number:
Japanese Patent JPS6420731
Kind Code:
A
Abstract:

PURPOSE: To prevent substantially the production of sense of disorder for a reception signal against multi-path noise by combining the diversity system and a predicting system.

CONSTITUTION: A couple of radio reception antennas 1A, 1B arranged for the diversity and a changeover circuit 2 switching the antennas selectively, a circuit 3 detecting an antenna reception signal from a changeover circuit and a circuit 5 detecting multi-path based on the output signal of the detection circuit, an antenna switching control circuit 6 in response to the 1st multi-path detection signal S5A of the multi-path detection circuit to energizing the antenna switching circuit and a digital signal correction circuit 7 connected to the output stage of the detection circuit and connected in series with an A/D converter, a signal prediction circuit and a D/A converter, are provided. Then the digital signal correction circuit 7 responds to the 2nd multi-path detection signal S5B of the multi-path detection circuit and a predicting signal is outputted as to the switched antenna signal at the generation of multi-path. Thus, the effective signal generating means against noise is obtained.
