MULTI-RATE TRANSMITTING AND RECEIVING APPARATUS USING MULTI-CARRIERS, AND A MULTI-RATE SYSTEM CAPABLE OF ACQYURING A FREQUENCY DIVERSITY BY MULTIPLEXING USER DATA

摘要

PURPOSE: A multi-rate transmitting and receiving apparatus using multi-carriers, and a multi-rate system are provided to acquire a site diversity gain on an uplink and a downlink by using an identical code during a process of moving among cells. ;CONSTITUTION: A data generating part(101) generates the data transmitted to a receiving device. An encoder/interleaver(103) encodes/interleaves the transmission data. A mapper(105) converts output data of the encoder/interleaver. A pilot inserting unit(107) inserts output data of the mapper and multiplexing data of a pilot. A user block allocator(109) allocates the user corresponding to each block. The coding unit(111) performs a coding operation on a data row of each user. A diffusing code generator(113) generate a diffusing code used in a data multiplexer(115). The data multiplexer multiplexes data for each user, transferred from the coding unit, according to each block. A protecting interval inserting unit(117) inserts a protecting interval for the data outputted by the data multiplexer.;COPYRIGHT KIPO 2011
