DEMULTIPLEXER FOR CHANNEL INTERLEAVER AND METHOD OF DEMULTIPLEXING TRANSMITTER AND ELEMENT IN DIGITAL WIRELESS COMMUNICATION SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a demultiplexer for a channel interleaver in a communication system using either of or both of multiple carriers and transmitter diversity. PSOLUTION: The demultiplexer 402 includes a distribution module that distributes data bits in succession to successive transmitter antennas; and a switching module coupled to the distribution module. The distribution module routes one data bit to each antenna such that no data bit is routed to the same antenna as the previous data bit. The switching module controls the distribution module to skip an antenna once each time a predefined number of data bits has been routed. Alternatively, the switching module may control the distribution module to repeat an antenna once each time a predefined number of data bits has been routed. The transmitter antennas may, in the alternative, be different carrier frequency bands. PCOPYRIGHT: (C)2011,JPO&INPIT
