A NOVEL APPROACH FOR DESIGNING HYBRID TURBO CODES USING DOUBLE STAGE INTERLEAVER

Interleaver being an integral component of the communication system. The interleavers tend to avoid the burst errors by splitting the signals and t he turbo codes are used to reduce the BER. The paper will describes a new approach to design a new class of turbo codes that would reduce the decoder complexity, such turbo codes will be known as modified turbo codes taking Decoder complexity as the main pa rameter consideration for the design of modified turbo codes. T he author presents the design of two types of modified turbo codes, the one would be called as Low Complexity Hybrid turbo codes (LCHTC) and the other one Improved Low Complexity Hybrid Turbo C odes (ILCHTC).
