Appeal No. 2006-0439
Application 09/765,754
separating the stream of information bits into a plurality of different portions;
associating each of the portions of the information bits with one of a plurality
of levels;
applying at least one code to the portion of the information bits of each level in
a designated subset of the plurality of levels such that the portions of the information
bits for one or more levels in the designated subset are coded while the portions of the
information bits for one or more levels not in the designated subset are uncoded; and
utilizing both the coded portions of the information bits and the uncoded
portions of the information bits to select modulation symbols for transmission in the
system;
wherein the stream of information bits comprises at least one frame of
information bits separated into a plurality of different classes of bits, each class of bits
comprising a plurality of contiguous bits of the frame, and wherein each of the
portions of the stream of information bits comprises a corresponding one of the
different classes of bits within the at least one frame, and wherein the at least one code
is selected so as to provide different amounts of error protection for at least a subset of
the different classes of bits.
The following references are relied on by the examiner:

Claims 1 through 4, 6 through 8, 17, 19, 23 and 25 stand rejected under 35
U.S.C. § 102(b) as being anticipated by Fazel. All remaining claims on appeal stand
rejection under 35 U.S.C. § 103. As evidence of obviousness as to claim 9 through 13
and 20 through 22, the examiner relies upon Fazel only, to which the examiner has
added Herzberg and Clayman as to claims 5 and 15, separately added Cloonan as to
claim 14, and separately added Chouly as to claim 24.
