摘要： A wireless system in which a pilot signal is transmitted in such a manner as to restrain error between the SIR of a data channel and that of the pilot signal, thereby improving wireless transmission quality. A specific pilot signal generator generates a specific pilot signal whose power and spreading ratio are identical with those of the data channel. A data channel generator receives propagation environment information and generates the data channel with a transmission format corresponding to the received propagation environment information. A wireless transmitter transmits the specific pilot signal and the data channel. On detecting the specific pilot signal, a propagation environment information notifier measures the SIR of the specific pilot signal, then generates propagation environment information corresponding to the measured SIR, and notifies the wireless transmitting unit of the generated information. A data channel receiver receives the data channel and processes the received data channel.

摘要： A cubic metric calculator performs a calculation of a time average of power of the amplitude of a transmission signal when a cubic metric value is calculated as a product-sum operation between a transmission power-dependent term including an amplitude value depending on the transmission power of a transmission signal and a time average term including only a modulation parameter not depending on the transmission power of the transmission signal. When the transmission signal is transmitted, the operator inputs the amplitude value to calculate the transmission power-dependent term, reads the value of the time average term from coefficient memory, and performs the product-sum operation using an operation result of the transmission power-dependent term and the read value of the time average term, thereby calculating a time average of the power of the amplitude of the transmission signal.
