Enhanced trellis extracted synchronisation technique for practical implementation

Intrinsic synchronisation algorithms increase the data throughput of a system at the expense of processing. The trellis extracted synchronisation technique (TEST) is an intrinsic synchronisation algorithm for the combined decoding and synchronisation of error control block codes. This paper illustrates two enhancements to the TEST algorithm which improves synchronisation performance and reduces processing. Inherent errors due to the linearity and cyclic properties of block codes are corrected. A simple estimate of future synchronisation points in a data stream can be efficiently used to decrease the processing with no expense of coding performanc
