英文摘要	High performance network over coax(HINOC)has become next-generation broadcasting network(NGB)industry standard of China, as well as International Telecommunication Union(ITU)telecommunication standard, which adopts orthogonal frequency division multiplexing(OFDM)technique and high order modu- lation formats. As is known, in OFDM system, phase noise destroys the orthogonality of the subcarriers and degrades the performance of the system especially when the data are transmitted in high order modulation formats. In this paper, we propose a high spectral efficiency OFDM system utilizing a novel and almost blind phase noise compensation method mainly used for high performance coaxial transmission. In our system, some subcarriers, which remain to transmit unknown useful data in lower order modulation formats, are selected as pseudo pilots instead of pilots to suppress phase noise effectively and high spectral efficiency can be achieved with the aid of puncturing mechanisms. Simulation results show that the proposed pseudo pilot-aided OFDM system can achieve the performance of the pilot-aided counterpart yet acquiring higher spectral efficiency.; supported by National Natural Science Foundation of China,State Key Laboratory of Advanced Optical Communication Systems and Networks, China; 中国科学引文数据库(CSCD); 6; 062303-1-062303-9; 60
