Claim of US Patent No. 9,083,400

9. A multi-antenna signal processing device in an uplink system, comprising: a scrambling module, a modulation module, a layer
mapping module, a pre-coding module, a transmission pre-coding module, a resource mapping module and a Single Carrier Frequency
Division Multiple Access (SC-FDMA) signal generation module, wherein
the scrambling module is configured to scramble a coded bit sequence corresponding to each codeword and to send a scrambled
bit sequence corresponding to each codeword to the modulation module;

the modulation module is configured to modulate the scrambled bit sequence corresponding to each codeword and to send a modulated
complex symbol corresponding to each codeword to the layer mapping module;

the layer mapping module is configured to perform layer mapping on the modulated complex symbol corresponding to each codeword
and to send an obtained complex symbol on each layer to the pre-coding module;

the pre-coding module is configured to perform pre-coding on the complex symbol on each layer and to send an obtained complex
symbol corresponding to each transmitting antenna port to the transmission pre-coding module;

the transmission pre-coding module is configured to perform transmission pre-coding on the complex symbol corresponding to
each transmitting antenna port and to send an obtained complex symbol corresponding to each transmitting antenna port that
has gone through transmission pre-coding to the resource mapping module;

the resource mapping module is configured to perform resource mapping on the complex symbol corresponding to each transmitting
antenna port that has gone through transmission pre-coding and to send an obtained complex symbol corresponding to each transmitting
antenna port that has gone through resource mapping to the SC-FDMA signal generation module; and

the SC-FDMA signal generation module is configured to perform SC-FDMA signal generation on the complex symbol corresponding
to each transmitting antenna port that has gone through resource mapping and to transmit a resulted signal from each transmitting
antenna port.
