Abstract
Background & Objective: The channel coding improves the performance of the mobile network link by adding redundant bits in the message in order to detect and correct the errors occurred during transmission of the data. The traditional method involved in channel coding for GSM has a number of operations, its computation time and complexity were very high which increases the latency in communication. To reduce the latency, we propose a novel and efficient Look Up Table (LUT) based implementation using Fire codes for Control Channel Coding in GSM.
Methods: In this research paper, a new and competent LUT based implementation towards channel coding in GSM is projected. This proposed technique will significantly decrease the computation time and number of cycles with less complexity. The suggested method improvises the coding scheme of FIRE codes adopted in GSM communication system by reducing the number of shift operations to zero.
Results: The proposed LUT based method outperforms the conventional method by reducing the number of cycles, XOR operations, shift operations, execution time and memory consumption. Our algorithm achieved around 89% improvement in Fire code implementation compared to Shift and XOR method, which is, considered as significant growth for GSM communication system.
Conclusion: The proposed technique demonstrated the significant improvement in reducing the latency and memory usage in comparison to the conventional method.
Keywords: GSM (2G), TCH (voice) coding, control channel coding, fire codes, Look Up Table (LUT), XOR.
