DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Information Disclosure Statement
The references listed in the Information Disclosure Statement(s) filed on 12/5/2024 have been considered by the examiner (see attached PTO-1449 form or PTO/SB/08A and 08B forms).
Claim Rejections - 35 USC § 112
Claim 13 is rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Claim 13 recites the limitations "the prefix" and “the suffix” in lines 2 and 3, respectively. There is insufficient antecedent basis for this limitation in the claim. However, it appears that the claimed dependency of claim 13 to claim 2 may be a typographical error, and should be “claim 12” which is further dependent on claim 7, which does provide the proper antecedent basis for the indicated subject matter of claim 13. It is suggested to amend claim 13 to be dependent on claim 12.
Allowable Subject Matter
Claims 1-12, 14-20 are allowed.
Claim 13 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
The following is a statement of reasons for the indication of allowable subject matter: The claims of the present application are directed to a device for generating a signal, the device comprising:
processing circuitry configured to:
obtain a set of input symbols; and
modulate a plurality of chirp signals, w[m, n], based on the set of input symbols,
wherein the plurality of chirp signals, w[m, n], are based on a bivariate polynomial, p(m, n), of input symbol index m and chirp signal time index n, and
wherein the bivariate polynomial p(m, n) comprises a first coefficient c1 of a quadratic term of the chirp signal time index n and a second coefficient c2 of a quadratic term of the input symbol index m.
The closest prior art of Erseghe et al. (NPL – “Multicarrier Architecture Based Upon the Affine Fourier Transform” – cited in an IDS), discloses all of the subject matter described above.
However, the prior art does not further disclose:
wherein the first coefficient c1 comprises a sum of a system parameter c(1,0) and a channel parameter ε1.
This limitation, in combination with the rest of the recited subject matter, distinguishes the claims over the prior art, rendering them allowable.
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
Lu et al. (US2020/0355487) discloses method of generating and detecting chirp signals with quadratic coefficient terms.
