DETAILED ACTION
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claims 1-18 are pending and examined.
Claim Objections
Claims 5, 11-16 are objected to under 37 CFR 1.75(c) as being in improper form because a multiple dependent claim cannot depend from any other multiple dependent claim. For example. See MPEP § 608.01(n). Accordingly, the claims have not been further treated on the merits.

Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Luo.
Regarding dependent claim 10, Luo real-portion matrix +M read coefficients, imaginary-portion matrix +M imaginary coefficients and imaginary-portion negative matrix -M read coefficients. However, Luo does not explicitly teach the parameter matrix is represent as:

However, it would have been obvious to one with ordinary skill the in art to realize that representative of a parameter matrix is a matter of design choice, which depends on the intended calculation.
