Summary:The importance of convolutional codes is well established. They are widely used to encode digital data before transmission through noisy or error-prone communication channels to reduce occurrence of errors and memory. This paper presents novel decoding technique, memoryless Hybrid Register Exchange with simulation and FPGA implementation results. It requires single register as compared to Register Exchange Method (REM) & Hybrid Register Exchange Method (HREM); therefore the data trans-fer operations and ultimately the switching activity will get reduced.
