Title:
MOBILE COMMUNICATION EQUIPMENT
Document Type and Number:
Japanese Patent JPH09172427
Kind Code:
A
Abstract:

To improve the quality of fast data transmission under multi-path phasing.

In an equipment on the side of a base station 1 and the equipment on the side of a mobile station 21 using a TDD(time division duplex) system, a serial/parallel converter 3 converts the fast transmission data series 2 of one series to plural slow data series at the time of transmission, a multi- carrier modulator 4 modulates them through the carrier waves of plural difference frequencies and a transmission signal switching device 5 selects one with a better propagating characteristic of first and second antennas 8 and 9 for each carrier wave through the use of input information from a reception level detection circuit 10 to transmit. The maximum rate synthesis of the received signal of each antenna can be executed independently by each carrier wave, error correcting encoding and interleave, which replaces the time order of data string, can be executed before dividing fast data to slow data in stead of a received signal switching device 11.
