Adaptive Simplified Successive Cancellation for Polar Codes Based on Frozen Bits
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 4
Abstract
Polar codes have been recently proposed as the first low complexity of error correcting codes for wireless channels that can provably achieve the capacity of symmetric binary-input memory less channels. Here, the bit error rate performance of finite-length polar codes is performed under Successive-Cancellation decoding. In existing ASM controller is used in high radix computation, utilizes high hardware resources that increase implementation complexity with reduced performance. To overcome this by using proposed architecture, the length of polar code N can be reduced from N-1 to N/2-1 from the decoding latency of the code, it can replace high hardware resources in merged processing elements to control the decoding by state transition method results low power consumption. The 8-point polar coder is proposed that can be easily combined to form efficient Npoint polar coder architectures, so that it can achieve parallelism and bit-pipelining techniques result in low power operation and easily expandable architecture with respect to data and/or co- efficient word length. Finally, in this paper the position of frozen bits and architecture of 8-bit SC decoder was analyzed. Our coding scheme also achieves the capacity of the physically degraded channel with better error control performance.
