自适应调制的改进
摘要：
一种无线通信系统包括：可操作为使用多种调制模式通过通信信道发送和接收信号的第一收发器(2)和第二收发器(4)。接收使用第一调制模式通过通信信道从第一收发器(2)发送到第二收发器(4)的第一信号，以及从通信信道的测量值确定在第二收发器(4)处接收第一信号的第一类型均衡器的第一信道均衡特性。从第一信道均衡特性确定用于第二调制模式的第二类型均衡器的第二信道均衡特性。确定第二信道均衡特性与第一信道均衡特性之间的测量值的差，并且至少部分根据测量值从第一收发器(2)选择用于通过通信信道进行发送的第二调制模式。
摘要（英）：

A wireless communication system includes first and second transceivers operable to transmit and receive signals over a communication channel using a plurality of modulation modes. A first signal is received which has been transmitted using a first modulation mode over the communication channel from the first transceiver to the second transceiver, and a first channel equalization characteristic for an equalizer of a first type for receiving the first signal at the second transceiver is determined from measurements of the communication channel. From the first channel equalization characteristic, a second channel equalization characteristic is determined for an equalizer of a second type for a second modulation mode. A measure of a difference between the second and the first channel equalization characteristics is determined, and the second modulation mode is selected for transmission over the communication channel from the first transceiver at least in part in dependence on the measure.
