ABSTRACT:
By providing a interference power estimation unit obtaining the power of interference in a common pilot signal with ten symbols in one slot and outputting the power of interference as the estimate of the amount of interference in the data signal's pilot signal and a signal-to-interference power ratio calculation unit calculating a signal-to-interference power ratio (SIR) using an output of the interference power estimation unit, in a spread spectrum communication method, a correct SIR can be estimated even when the number of symbols of an individual pilot signal in the slot of the data channel is small.
