Title:
RADIO TRANSMISSION SYSTEM, AND RADIO STATION AND METHOD USED FOR SAME
Document Type and Number:
WIPO Patent Application WO/2007/114049
Kind Code:
A1
Abstract:
A radio transmission system capable of simultaneously transmitting data by
radio to stations. The radio transmission system comprises radio stations
for transmitting/receiving data and constitutes a system for path diversity
by the radio station on the transmitting side, a multipath transmission channel,
and the radio station on the receiving side. At least one of the radio stations
determines delay amounts from a reference timing at which the simultaneous transmission
is performed in the radio transmission system and a symbol waveform on which a
modulated waveform is based according to a response packet sent in response to
a request packet for the simultaneous transmission to the stations transmitted
by the radio station or another radio station. Each difference in the delay amounts
is set to a predetermined delay resolution or higher for each symbol waveform
and the difference between the maximum value and the minimum value of the delay
amounts is set to a predetermined delay upper-limit or lower.
