Hello, I am looking for someone to write an article on Error Detection and Correction for ATM Technology. It needs to be at least 4250 words. FEC corrects the corrupted data rather than retransmitting it again. We have evaluated the performance of the proposed method for the random integer, information, and speech signal. The results show that the errors have been detected and corrected successfully. To obtain the best bit error rate, the proposed method has been evaluated for different code rates. To assess the performance of the proposed method we have compared it with other well-known code techniques. The comparison results are given in terms of BER versus SNR (Signal-to-noise ratio). The comparison results show that the proposed method is superior to others.
ATM is a superb-speed communication technique that reached nearly a cosmopolitan admittance in the latter ages. ATM gives a superb-bandwidth, low-tardiness multiplexing/ switching (MUX/SW). A cell is ATM (MUX/SW)’s basic-unit. Its length=53 bytes: 48 data-bytes, 5 control-bytes such as a virtual-path-identifier, virtual-channel-identifier and a cyclic-redundancy-checksum for header error control.
ARQ and FEC are substantial mechanisms for Reliability Amelioration. The data retransmission/closed-loop mechanism is the ARQ-precept in case of receptions errors. The state-information exchange between dispatcher and remit-tee is what ARQ needs. A delay of 1 round-trip-time is added upon each retransmission. So, for low-latency services, ARQ may not be workable in such a field. Therefore, FEC is an ersatz solution. It averts the ARQs blemishes and convenient for high-bandwidth-delay services. By Redundant-Information transmission with the Original Ones, FEC can rebuild the data again in case of data loss. FEC keeps sufficient. because of the redundant-information amount’s smallness.
Larry S. Reed & Solomon had contrived the R-S codes in 1960 [1]. which are efficacious in the deep-fades channel and considered as a structured sequence to be useful immensely in FEC for assortment communications to their .error-correction-strength in burst errors. They also wrote, "Polynomial codes over certain fields".
