Error Detection and Error Correction in Wireless Communication

Abstract

Wireless Communication links plays a vital role in robotics field. We need robust communication links through which we can send control commands to robots and also receive back the vital information like telemetry from the robots regarding its health and the required purposeful information for which this robot is used. Wireless communication links algorithm should be good enough, so that it can detect and correct the errors induced by noise present in the environment. This research is focused on the optimization and robustness of the wireless communication links used in various Robotics fields, whether these robots are involved with the field of aerial, land or sea. This algorithm has the capability to detect the single or multiple errors from the received packets. After detection of errors it can correct these errors to extract the required information. Through error correction technique implementation, robustness of the wireless communication link is increased and it also reduces the work load on communication link to some extent. This was due to retransmission of received corrupted data packet. A fast, low cost and low in processing power novel configuration of implementation of this algorithm is then proposed. The algorithm is then implemented in Embedded C and assembly language. Atmega Microcontrollers are used to fulfill the requirement of microcomputer. Required hardware is designed to fulfill the test of algorithm. After implementation of algorithm on hardware, a desktop application is developed in C sharp to compare the results on computer. The results of implemented algorithm are compared with already published bestknown results for the similar benchmark problems and improved results are presented. In the end, conclusions and future research directions are also identified.
