  • Automobile on-board and/or portable telephone system
    Patent number: RE37420
    Abstract: In an automobile on-board and/or portable telephone system capable of increasing the capacity of subscribers easily on the basis of changing of the information transmission bit rate, spread codes obtained by multiplying orthogonal spread codes (m in number) by a pseudo-random noise series are assigned to individual channels in the same cell in such a manner that the orthogonal spread codes are multiplied by some types of pseudo-random noise series having different phases, thereby making it possible to maintain the number of channels in the same cell at a value which is a multiple of the number of the orthogonal spread codes.
    Type: Grant
    Filed: June 21, 1999
    Date of Patent: October 23, 2001
    Assignee: Matsushita Electric Industrial Co., Ltd.
    Inventors: Nobuo Asano, Osama Kato
