Appeal No. 2002-0992
Application No. 09/116,018
Division Multiple Access (CDMA) mobile communications system. The invention serves
to eliminate interference signals received at a different angle than the reception angle of
the desired signal as well as multiple access interference signals included in signals
received at the reception angle of the desired signal.
Representative claim 1 is reproduced as follows:
1. A receiving method in a Code Division Multiple Access (CDMA) mobile
communications system, comprising the steps of:
controlling beam patterns and directions of an adaptive array antenna to
coincide with a reception direction of a desired signal;
forming a beam in the reception direction of the desired signal;
eliminating an interference signal received at a different angle than the
reception angle of the desired signal; and
eliminating multiple access interference signals included in signals
received at the reception angle of the desired signal.
The examiner relies on the following references:
Talwar 5,152,010 Sep. 29, 1992
Raleigh et al. (Raleigh) 6,101,399 Aug, 08, 2000
(filed June 16, 1995)
Claims 1-12 and 16 stand rejected under 35 U.S.C. § 103(a). As evidence of
obviousness the examiner offers Raleigh in view of Talwar.
Rather than repeat the arguments of appellant or the examiner, we make
reference to the main brief and the answer for the respective details thereof.
