Abstract—It is known that one of the essential building blocks
of turbo codes is the interleaver and its design using random,
semi-random (S-Random) and deterministic permutations. In
this paper, two new types of turbo code interleavers, Modified
Block S-Random (MBSR) interleaver and Modified Matched
S-Random (MMSR) interleaver are proposed. The design
algorithm for the new interleavers is described in depth, and the
simulation results are compared to the two new interleavers
with different existing interleavers based on the BER (Bit Error
Rate) performances of the turbo codes. Through the simulation,
we find a better performance of the MBSR interleaver than
random and practical interleavers. In addition, the
performance of MMSR interleaver is close to the code matched
interleaver at different frame sizes and with less complex
design.
