Appeal 2007-1083
Application 09/847,093
1 Claim 8 is representative of the invention and reads as follows:
2
3 8. A communication system comprising a radio transmitter
4 transmitting a signal which is interfered with by fixed reflectors
5 and moving reflectors, said system comprising an antenna, a
6 receiver and a multipath reduction subsystem comprising an
7 analog to digital converter, a real to complex converter, a
8 whitening filter with complex coefficients and a multipath
9 canceller comprising an array of complex delay-Doppler shift
10 coefficients, delayers of one sample and shifters of one
11 frequency increment, said array producing a residual from
12 which the interferences from said fixed reflectors and said
13 moving reflectors have been removed, said multipath canceller
14 comprising a minimizer minimizing the mean square of said
15 residual over the said whitening filter coefficients and the said
16 multipath canceller delay-Doppler coefficients, said subsystem
17 comprising a spectrum restoring filter utilizing the said
18 whitening filter coefficients restoring said original signal

20 The Examiner objects to the disclosure under 37 C.F.R. § 1.71. (See
21 Final Rejection pp. 3-6.) The Examiner asserts (Answer 4) that the
22 Specification is so incomprehensible as to preclude a reasonable search of
23 the prior art. The reasoning by the Examiner is that it is unclear as to how
24 the invention can be made or used. (Final Rejection 4.) The reasoning
25 provided by the Examiner in both the Final Rejection and the Answer
26 implies or suggests that the disclosure is non-enabling and/or lacking written
27 description. The examples given by the Examiner are that there is no
28 discussion of how the filter weights are calculated or applied. The Examiner
29 contends (Final Rejection 4) that it is unclear where the removal of the
30 multi-path is discussed. The Examiner additionally contends that the
31 receiving and sampling of the signal is discussed, but that it is unclear as to
