Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Wireless communication standards make use of parallel turbo decoder for higher data rate at the cost of large hardware resources.  presents a memory-reduced back-trace technique, which is based on a new method of estimating backward-recursion factors, for the maximum a posteriori probability (MAP) decoding. Mathematical reformulations of branch-metric equations are performed to reduce the memory requirement of branch metrics for each trellis stage.

Comparative analysis of bit-error-rate (BER) performances in additive white Gaussian noise channel environment for MAP as ll as parallel turbo decoders are carried out. It has shown that a MAP decoder with a code rate of 1/2 and a parallel turbo decoder with a code rate of 1/3 have achieved coding gains of 1.28 dB at a BER of 10$$^{-5}$$-5 and of 0.4 dB at a BER of 10$$^{-4}$$-4, respectively. In order to meet high-data-rate benchmarks of recently deployed wireless communication standards, very large scale integration implementations of parallel turbo decoder with 8---64 MAP decoders have been reported. Thereby, savings of hardware resources by such parallel turbo decoders based on the suggested memory-reduced techniques are accounted in terms of complementary metal oxide semiconductor transistor count. It has shown that the parallel turbo decoder with 32 and 64 MAP decoders has shown hardware savings of 34 and 44 % respectively.
