    Abstract

    :

    This paper describes an error correction mechanism based on Rate-Compatible Insertion Convolutional (RCIC) Turbo codes. Rate-compatible Turbo codes are part of numerous mobile communication systems (LTE). The code rate about the fixed-rate mother Turbo code is adjusted by bit repetition and bit puncturing. The given CRC bits are encoded with the help of RCIC encoder. Lower code rates can be created by introducing known (dummy) bits into the information bit sequence before Turbo coding. Then, the resultant bits are modulated and demodulated based on Quadrature Amplitude Modulation (QAM). The demodulated signal is interleaved and deinterleaved in order to correct the burst errors and it helps to reduce the complexity. Finally, the deinterleaved signal is decoded using Linear Block Codes (LBC), hamming codes and cyclic decoder. The experimental result shows that the proposed method results higher throughput than the existing RCIC encoder method.
