Patent ID: 7515628

Claim:
A portable terminal set comprising a receiving means for receiving data from a plurality of base stations, a de-spreading means for de-spreading the data received by the receiving means, a combining means for combining the same data from the base stations de-spread in the de-spreading means, a decoding means for decoding the data combined in the combining means, a selectively combining means for selectively combining the decoded data from the decoding means, a detecting means for detecting any defect in the selectively combined data from the selectively combining means, and a control means for controlling the operation of the entire portable terminal set, wherein: the portable terminal set further comprises: a first counting means for counting a time required for the processes in the de-spreading means, the combining means, the decoding means, the selectively combining means and the detecting means; an off-set time counting means for counting an off-set time from the start of data reception from a base station till the start of data reception from a different base station; and when the detecting means detects no defect in the data and also when the time counted in the first counting means is shorter than the off-set time, the control means interrupts the process in the de-spreading means, the combining means and the decoding means on the data from the different base station.
