Title:
RADIO TRANSMITTER
Document Type and Number:
Japanese Patent JPH09233007
Kind Code:
A
Abstract:

To ensure excellent transmission quality at a low cost while flexibly adapting to diversified fluctuation in a transmission characteristic of a radio transmission channel by providing a transmission equalization means keeping an equal equalization characteristic to each equalization means compensating transmission distortion.

Demodulation means 121-12N demodulate individually a received wave to generate base band signals. Equalization means 131-13N compensate transmission distortion caused in the base band signals at a radio transmission channel. Modulation means 161-16N receive the base band signals being transmission objects via transmission equalization means 151-15N and apply modulation processing to the base band signals to generate transmission waves. The transmission equalization means 151-15N keep equalization characteristics individually equal to those of the equalization means 131-13N in interlocking with the equalization means 131-13N. Thus, the transmission distortion for a transmission paths from antennas 111-11N to antennas of opposed radio stations is compensated in preceding over the transmission.
