Title:

COMMUNICATION SYSTEM, COMMUNICATION APPARATUS AND COMMUNICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2010/122749

Kind Code:

A1

Abstract:

In a wireless communication system, a communication apparatus at a transmission end comprises a reference signal generating unit that generates, as reference symbols to be transmitted together with transmitted data, a sequence of reference symbols based on a pseudo noise sequence. A communication apparatus at a reception end can use the sequence of reference symbols, which were generated by the reference signal generating unit, to determine a signal reception status with the interference with the reference signal suppressed or reduced.
