摘要：
Sample signals P0(0) to P0(N−1) are input for each symbol of a multiplexed transmission sample or transmission chip. The sum of a particular pair of sample signals (for example, a pair of P0(0) and P0(N/2)) is obtained by an adder for each pair of sample signals, and a signal the power of which is halved by attenuating the sum with an attenuator is generated and output as a dispersion signal P1(N/2). Additionally, a difference between the pair of the sample signals is obtained by a subtractor, and a signal the power of which is halved by attenuating the difference with an attenuator is generated and output as a dispersion signal P1(0). The dispersion signals P1(0) and P1(N/2) are made to respectively correspond to first and second subsymbols, which are configured by partitioning the symbol.
摘要（中）：
针对多路传输采样或传输芯片的每个符号输入采样信号P 0（0）至P 0（N-1）。 通过加法器为每对采样信号获得特定的一对采样信号（例如，一对P 0（0）和P 0（N / 2））的和，并且其功率为 产生通过用衰减器衰减和减半，并作为色散信号P 1（N / 2）输出。 此外，通过减法器获得一对采样信号之间的差异，并且产生通过衰减与衰减器的差来减弱其功率的信号，并将其输出作为色散信号P 1（0）输出。 分散信号P 1（0）和P 1（N / 2）分别对应于通过划分符号来配置的第一和第二子符号。
