Patents by Inventor Yoshitaka Aramaki

Yoshitaka Aramaki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Radio communication terminal apparatus and radio communication base station apparatus
    Patent number: 7535864
    Abstract: A CDMA radio receiving apparatus which receives a slot which has a long code group identification short code at a point where a long code is masked. The apparatus includes a detector that detects a phase of the long code in association with a pattern that appears over successive slots and comprises the long code group identification short code. The apparatus also includes a correlator that performs correlation processing in association with the phase detected by the detector to identify the long code.
    Type: Grant
    Filed: March 10, 2006
    Date of Patent: May 19, 2009
    Assignee: Panasonic Corporation

  • CDMA radio communication apparatus
    Patent number: 6370134
    Abstract: A transmission side transmits a frame in which a masked symbol spread with a common short code to all base stations is prepared at equal intervals and a symbol spread with a long code group identification is multiplexed in the masked symbol according to the predetermined pattern. A reception side detects a pattern of the multiplexed symbol in pattern detecting section 113 as detecting a long code identification short code to acquire a long code phase. Based on the long code phase, a long code included in a long code group is searched.
