Radio communication apparatus, transmitter apparatus and receiver apparatus
First Claim
1. (Twice Amended) A radio communication device comprising:
- a transmitter (15) including a multiplexing circuit (1) for multiplexing broadcast waves including a ground broadcast wave, a satellite broadcast wave or a cable television broadcast wave and signal waves dedicated to the user modulated by a modulator which are different from said broadcast waves, and transmitting, as millimeter-waves, multiplexed waves in which said broadcast waves and said signal waves dedicated to the user are allocated in different positions on a frequency axis; and
a receiver (29) including a output processing circuit (45) for receiving said multiplexed waves transmitted as millimeter-waves from said transmitter, distributing said broadcast waves, and demodulating said modulated signal waves dedicated to the user, wherein said broadcast waves and said signal waves dedicated to the user are simultaneously and independently radio-connected to an electronic device.

Abstract
The present invention provides a radio communication device, a transmitter and a receiver capable of handling a plurality of signal waves. A radio communication device has a millimeter-wave transmitter (15) and a millimeter-wave receiver (29). Millimeter-wave transmitter (15) includes a multiplexing circuit (1), a millimeter-wave up-converter (4) and an antenna (3), and the millimeter-receiver includes an antenna (31), a millimeter-wave down-converter (32) and an output processing circuit (45). The signal waves dedicated to the user are modulated by a modulation circuit (121 to 124) so as to be allocated between the ground broadcast waves and satellite broadcast waves. The frequencies are multiplexed in an intermediate frequency band, after that, the multiplexed frequencies are converted into a millimeter-wave band and the resultant is transmitted. On the reception side, the multiplexed waves are down-converted, separated to signal waves and demodulated.
