Abstract:
A mobile communication apparatus, comprising:an antenna for receiving signals transmitted from a plurality of base stations; demodulating means for demodulating a single received signal of a plurality of received signals received by said antenna; detecting means for repeatedly and successively detecting reception energy values of said plurality of received signals; and control means for calculating, whenever said detecting means detects each of said reception energy values of said plurality of received signals, an average value of said reception energy values, comparing said average value with the reception energy values, and demodulating a reception signal having a largest reception energy value with said demodulating means, wherein said control means uses a number N of reception energy values of said plurality of received signals to calculate said average value, wherein N is at least two, wherein said control means stores said number N of reception energy values of said plurality of received signals and reads said number N of reception energy values to calculate said average value, and wherein said control means stores the number N and a latest average value Aold of reception energy values, and obtains a newest average value Anew by using a detected newest reception energy value Enew, where Anew={AoldÃ—(Nâˆ’1)+Enew}/N.
