Single - Bit Error Correction Circuit for ATM Interfaces

Electronics Letters, IEE, Vol. 31, No. 8, April 1995, pp. 617-618.

Abstract: Cell switching systems use cyclic codes for protecting cell headers from transmission errors either by detecting multiple errors or by correcting single-bit errors. The Letter presents a new method for implementing single-bit forward error-correction functions by minimising the complexity of parallel CRC circuits, resulting in low hardware complexity and high operational speed. The method does not use a look-up table for determining the corrupted bit position, but implements a repetitive algorithm for matching the generated syndrome. The implementation of the proposed method to an ATM interface using field programmable gate arrays is also described.
