A receiving antenna unit 28 receives channel state information from each terminal, a channel matrix H is obtained. A transmit weight/interference coefficient calculation unit 24 calculates a transmit weight and an interference coefficient based on channel matrix. The transmit weight is input to transmit weight multiplication units 17 and 23. The interference generation unit 15 generates an interference signal based on the interference coefficient. An interference subtraction unit 13 subtracts the interference signal from a desired signal. A modulo unit 14 adds a signal so that amplitude of an information signal output from the interference subtraction unit 13 falls within a constant range. A signal multiplexing unit 18 performs spatial multiplexing to the signal performed nonlinear arithmetic.

摘要： When applying inflated lattice precoding (ILP) transmission to a multi-carrier scheme, there arises a need to notify coefficient α thereof per sub-carrier. Applying ILP transmission has proven difficult since multi-carrier schemes such as those widely adopted in mobile communication systems, etc., in recent years have an extremely large number of sub-carriers and the information volume of the control signal becomes extremely large. As such, at a transmitter device B, coefficient α is inputted to a 1/α multiplier part 15, and a DRS from a dedicated reference signal (DRS) generator part 11 is multiplied by 1/α and transmitted. At a receiver device C, an estimated signal is obtained by performing a remainder process at a reception modulo operator part 51 using a modulo width determined based on the DRS, without performing a process of a reception coefficient multiplier part with respect to a reception signal.
摘要翻译：当将充气格子预编码（ILP）传输应用于多载波方案时，需要通知每个子载波的系数α。由于近年来在移动通信系统等中广泛采用的多载波方案具有非常多的子载波，并且控制信号的信息量变得非常大，所以应用ILP传输被证明是困难的。这样，在发送装置B中，将系数α输入到1 /α乘法器部15，将来自专用基准信号（DRS）发生部11的DRS乘以1 /α并进行发送。在接收机装置C中，通过使用基于DRS确定的模数宽度，在接收模运算器部分51执行余数处理，而不对接收信号执行接收系数乘法器部分的处理，来获得估计信号。
