摘要：

We show that the optimum length-nu guard sequence for block transmission over a linear Gaussian-noise dispersive channel with memory nu is a linear combination of the N information symbols of the block. A closed-form expression for the optimum guard sequence is derived subject to a total average energy constraint on the information and guard symbols. The achievable channel block throughput with the optimum guard sequence is compared with that achievable with two common guard sequence types, namely zero stuffing and cyclic prefix.
