Channel coding is commonly incorporated to obtain sufficient reception quality in wireless mobile communications transceiver to counter channel degradation due to inter-symbol interference, multipath dispersion, and thermal noise induced by electronic circuit devices. High speed and high throughput hardware for encoder and decoder could be useful in communication field. Due to the channel achieving property, the GOLAY code has become one of the most favorable error-correcting codes. In this paper, a new algorithm has been proposed for CRC based encoding scheme, which devoid of any linear feedback shift registers (LFSR). In this architecture, our work is to design a GOLAY code based encoder and decoder architecture using CRC processing technique. The other approach is to design a Bloom filter with hamming distance based fast error detection and correction methodology and this work is to improve the secure data transmission. The bloom filter system is to identify the error bit location using the redundant bits add process and to correct the error for XOR based distance calculation process. The Bloom filter architecture is used to set the hash value for allocated transmitted data sequence and to improve the fault identification methodology. This method is to optimize the decoder structure and effectively identify the error location, then to correct to error using bit reverser logic process.
