In this study, from a more practical point of view, the authors develop an improved transmitted reference pulse cluster (iTRPC) scheme. Based on a recently proposed transmitted reference pulse cluster (TRPC) structure, each pulse cluster is broken into reference pulse clusters (RPCs) and data pulse clusters (DPCs). It is observed that by inserting a number of zeros at the end of each RPC and each DPC, inter pulse interference can be dramatically reduced. This also results in more multi-path delayed power being captured for data detection. The performance of the proposed iTRPC scheme is analysed and compared with that of traditional TR and the original TRPC (oTRPC) system. Simulations verify that this iTRPC scheme, with quite low-complexity and not extra energy requirements, achieves more than 7 dB performance improvement over the oTRPC scheme.
