摘要： A next alternative storing memory that stores a next alternative code is disposed. When demodulated data cannot be obtained, in the case that a code as a next alternative has been stored in the next alternative storing memory, a partial searching process is performed with the code so as to demodulate data.
When data can be demodulated, a searching process is performed with the code.

摘要： With respect to each of received signals from a plurality of base stations, the average value is calculated by using detected reception energy and reception energy detected in the past, to determine a received signal to be demodulated by comparing the average values. Thereby, a further accurate reception energy can be obtained in comparison with the case of simply detecting reception energy, even if the detected reception energy temporarily and greatly varies, thus further avoiding malfunction in comparison with the prior art.

摘要： A receiving apparatus is used in a mobile communication system which transmits and receives spread spectrum signals between a base station and a mobile station. In the receiving apparatus, the timing detection region of a spread spectrum signal is set in accordance with the intermittent receiving period. If it is difficult for the mobile station to establish synchronization with the base station over a long intermittent receiving period due to errors accumulated in the oscillator of the mobile station, the window serving as the search area is expanded. Accordingly, the capability of detecting the timing is increased, and errors of the oscillator are compensated. Thus, re-synchronizing operation and intermittent receiving operation are reliably performed. As a consequence, even by the use of a low-precision and simple-structured oscillator in the mobile station, a low-powered receiving apparatus in which an intermittent receiving operation having a longer period is performed is provided.

摘要： When a distortion is compensated by a predistorter method, a distortion can satisfactorily be compensated-by a simple arrangement. A limit operation can be made in such a manner that when a generated predistortion signal is held at a value smaller than a first level, this predistortion signal is not added to an input signal and that when a generated predistortion signal is held at a value larger than a second level which is larger than the first level, this predistortion signal is added to an input signal as a predetermined fixed value.
