Application 10/177,732
that are matched to the channel. The method estimates coefficients for the
basis functions using real-time data by solving a set of linear equations to
thereby estimate the channel (Specification 2 and 3).
Claim 1 is representative of the claims on appeal, and it reads as
follows:
1. A method for estimating a channel, comprising the steps of:
employing one or more basis functions that describe said channel
based on statistics of said channel;
employing one or more waveforms that are matched to said channel;
and
estimating coefficients for said basis functions using real-time data by
solving a set of linear equations to estimate said channel.
The prior art relied upon by the Examiner in rejecting the claims on
appeal is:
Alard US 6,263,029 B1 Jul. 17, 2001
Siala US 6,674,740 B1 Jan. 6, 2004
(filed Aug. 13, 1999)
The Examiner rejected claims 1 to 17 under 35 U.S.C. § 101 as being
directed to nonstatutory subject matter. The Examiner rejected claims 1, 2, 4
to 9, 13, and 17 to 20 under 35 U.S.C. § 102(e) based upon the teachings of
Siala. The Examiner rejected claim 10 under 35 U.S.C. § 103(a) based upon
the teachings of Siala and Alard.
Appellant contends that the nonstatutory subject matter rejection is
without merit because the claimed “transformation to a channel estimate or
in-band estimate provides a useful, concrete and tangible result” (Br 5;
Reply Br. 3). With respect to the prior art rejections, Appellant contends
