MULTI-CHANNEL TRANSMISSION SYSTEM, TRANSMITTING APPARATUS AND TRANSMITTING METHOD

摘要

A transmitter (1) comprises a spread code generating part (11) that uses the set values of adjustment parameters to generate spread codes from a row or column vector in a spread code matrix comprising trigonometric functions the arguments of which are the adjustment parameters; and a signal multiplexing part (12) that performs spread and multiplex processes of information using the spread codes. The transmitter (1) arranges the signals, which have been subjected to the spread and multiplex processes, onto a plurality of subchannels for transmission.
