Title:
TRANSMISSION DEVICE, RECEPTION DEVICE, COMMUNICATION SYSTEM, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2008/029704
Kind Code:
A1
Abstract:
A transmission device includes: a spread unit for spreading a transmission symbol
by using a spread code so as to generate a signal of each chip for each channel; a
code multiplexing unit for multiplexing chip signals of a plurality of channels
so as to generate a multiplexed signal; and an interleaver unit for rearranging
the order of the multiplexed signals in the spread direction by using a group of
multiplexed signals adjacent in the spread direction having a smaller number
of chips than the spread ratio of the spread code as a unit. It is possible to obtain
a frequency diversity effect and accurately obtain a symbol from the code-multiplexed
signals at the reception side.
