摘要

PROBLEM TO BE SOLVED: To provide a method and a device to integrate OFDM and CDMA techniques.;SOLUTION: A communication network 300 comprises a large number of communication systems such as base stations, access points, head ends, mobile units, subscriber, remote, and terminal units. At one site, a system 350 comprises: a CDMA transmitter 301 for transmitting information using CDMA to modulate a signal for wireless communication; and an OFDM receiver 302 for processing wireless communication with an OFDM signal format received form another point in a network. A switch 303 switches between the CDMA transmitter 301 and the OFDM receiver 302 and connects one of them with an antenna 310 at a time.;COPYRIGHT: (C)2014,JPO&INPIT
