Abstract:
1. A multi-antenna signal processing method in an uplink system, comprising: scrambling a coded bit sequence corresponding to each codeword to obtain a scrambled bit sequence corresponding to each codeword; modulating the scrambled bit sequence corresponding to each codeword to obtain a modulated complex symbol corresponding to each codeword; performing layer mapping on the modulated complex symbol corresponding to each codeword to obtain a complex symbol on each layer; performing pre-coding on the complex symbol on each layer to obtain a complex symbol corresponding to each transmitting antenna port; performing transmission pre-coding on the complex symbol corresponding to each transmitting antenna port to obtain a complex symbol corresponding to each transmitting antenna port that has gone through transmission pre-coding; performing resource mapping on the complex symbol corresponding to each transmitting antenna port that has gone through transmission pre-coding to obtain a complex symbol corresponding to each transmitting antenna port that has gone through resource mapping; and performing SC-FDMA signal generation on the complex symbol corresponding to each transmitting antenna port that has gone through resource mapping and transmitting a resulted signal from each transmitting antenna port.
