TRANSMITTING DIVERSITY AND RECEIVER PROCESSING METHOD IN TD-SCDMA SYSTEM

摘要

A transmitting diversity and receiver processing method in a TD-SCDMA system, comprises the following steps ( 1 ) dividing the transmitting antennas into two groups, wherein the transmitting symbols which maps the first group odd index coding channels are identical with the transmitting symbols which maps the second group even index coding channels, also, the transmitting symbols which maps the first group even index coding channels are identical with the transmitting symbols which maps the second group odd index coding channels, (2) the two groups of antennas using the same spreading code and scramble code for spreading and scrambling the transmitting symbols to form two groups of data segments, and adding different training sequences separately to the two groups of data segments to form the transmitting signals, wherein the antenna training sequence in a group keeps same, and the transmitting signals after intermediate frequency and radio frequency process are transmitted by two groups of transmitting antennas at the same time The present invention avoids the interleaving in time domain for same transmitting symbols in traditional time-space scheme and reduces the complexity of the receiver equalization.
