Abstract: A transmitting apparatus/method and a receiving apparatus/method in a multi-antenna system are provided to select the number of data streams adaptively to instantaneous changes of a channel, thereby preventing insufficiency of ranks, thereby considerably improving the bit error performance of a quantizing preprocessor. A transmitting apparatus(110) in a multi-antenna system comprises the followings: plural quantizing codebooks(113) which respectively correspond to each of data streams, and are formed by quantizing channel information between a transmitting antenna and a receiving antenna; a modulator(111) for modulating at least one data stream on the basis of an index of a stream mode included in information fed back from a receiving apparatus(120); and a quantizing preprocessor(112) which preprocesses the modulated data stream on the basis of a codeword index, selected from the quantizing codebooks(113) of the data stream corresponding to the stream mode of the index and included in information fed back from the receiving apparatus(120), and transmits the preprocessed data stream to the receiving apparatus(120).

Abstract: PURPOSE: A rake receiver reducing hardware complexity is provided to classify physical channels into the groups, and to make the branches as many as the number of the groups for each finger, then to share one branch by several physical channels of the groups. CONSTITUTION: Fingers(501,502) consist of code generators(511,521,531,541,551,561) for generating despread codes and despreaders(512,522,532,542,552,562) for despreading the received signals by the despread codes and outputting the symbols. Many deskew buffers(513,523,533,543,553,563) store the symbols, respectively. Symbol couplers(506,507,508) accord the time of the stored symbols and couple the accorded symbols. A controller(509) controls the operations of the fingers(501,502) and the symbol couplers(506,507,508). Specific pairs of the code generators(511,521,531,541,551,561), the despreaders(512,522,532,542,552,562), the deskew buffers(513,523,533,543,553,563), and the symbol couplers(506,507,508) form specific branches. Separably-received physical channels share the specific branches.
