Abstract
In order to realize the frame detection of signals which have different unique word (UW) lengths in multi-channel receiver, multiple UWs correlation detection algorithm is proposed. The algorithm judges whether the decision variable is greater than the threshold according to the UW length, from large to small, to determine whether a valid header is presented. Monte Carlo simulation is used to analyze the feasibility of the algorithm. In addition, a barrel shift register bank structure is adopted in hardware implementation, which can reuse multipliers to calculate the square magnitude of the correlation value and the energy of differential signal while traversing UWs. Simulations show that the proposed algorithm improves the detection performance and results in an easy-to-implement and resources saving structure.
