TRANSMITTER AND RECEIVER ADOPTING MC-DS/CDMA SYSTEM EMPLOYING SPATIOTEMPORAL TRANSMISSION DIVERSITY SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a transmitter and a receiver adopting the MC-DS/CDMA (Multiple Carrier-Directed Sequence / Code Division Multiple Access) system capable of obtaining a high speed transmission effect and a path diversity effect.

SOLUTION: The transmitter 1 includes: an encoding interleave means 12; a time space transmission diversity coding means 17; a pilot signal inserting means 14; a plurality of MC-DS/CDMA means 15; and a plurality of transmission antennas 16. The receiver 2 includes: a plurality of MC-DS/CDMA reception means 22; a spatiotemporal transmission diversity decoding means 25; a parallel/serial conversion means 23; and a decoding de-interleave means 24. In particular, the MC-DS/CDMA reception means 22 includes no RAKE synthesizer.
