| Summary: | 碩士 === 國立臺灣大學 === 電機工程學系 === 86 === In this thesis, we propose a long block code which is
constructed by using coset leaders
to connect Reed-Muller Codes. With our construction, the code
rate can be increased
without decreasing minimum distance and destorying the benign
trellis property, lower
number of state, of the original Reed-Muller Code. The
constructed codes are divided
into three groups corresponding to the number of states-- 4, 8,
and 16. When applied
to construt turbo code, the prolong block codes are prevailing
over Hamming codes and
more appropriate than convolutional codes for code rate higher
than 0.6. At last, we
apply the binary turbo code to a BCMIM for 8PSK which can
achieve a code rate of 2
information bits per symbol. For this new scheme where a
3-level partition is applied
to the 8PSK set, the binary turbo code is applied to the first
two levels and a Reed-
Muller code to the third level.
