Wireless communication system, wireless communication apparatus, and resource assignment method used therein
First Claim
1. A wireless communication system using a wireless communication apparatus having a plurality of transmission and reception antennas, wherein:
- the wireless communication apparatus comprising;
correspondence determining means for determining, upon producing first through M-th (M being an integer not smaller than
2) transmission signals, correspondence between first through K-th (K being an integer not smaller than
2) transmission sequences and frequency channels so that the correspondence is different for each transmission signal; and
extracting and combining means for extracting and combining, upon producing first through K-th demodulated sequences, M demodulated signals corresponding to the first through the K-th transmission sequences in accordance with the correspondence between the first through the K-th transmission sequences and the frequency channels.

Abstract
In a transmitting portion of a wireless communication apparatus, hopping pattern generating portions 16 and 17 produce hopping patterns independent from each other and specific to a transmitter. Subcarrier assigning portions 18 and 19 assign transmission symbol sequences to subcarriers 1 to R in accordance with the hopping patterns and produce frequency hopping signals. In a receiving portion of the wireless communication apparatus, a MIMO demodulating portion 37 combines and decomposes a FFT signal and produces a demodulated signal. Hopping pattern generating portions 38 and 39 produce unique hopping patterns corresponding to transmitters 1-1 to 1-K, respectively. Subcarrier extracting portions 40 and 41 extract, from the demodulated signal, components corresponding to the hopping patterns and produce the components as partial demodulated sequences, respectively.
