IEEE Transactions on Broadcasting, 1995
The research and development of OFDM/COFDM for digital television broadcasting has received considerable attention and has made a great deal of progress in Europe. OFDM/COFDM has already been implemented in digital audio broadcasting and is being considered for terrestrial digital television and HDTV broadcasting. The advantages of COFDM claimed by the

A Useful COFDM Demodulator for DVB-T
2009 Second International Workshop on Knowledge Discovery and Data Mining, 2009In this paper, a new kind of COFDM demodulator is proposed, which is conforming to the European DVB-T standard. The proposed prototype mainly contains four blocks: time synchronization, frequency synchronization, 2K/8K FFT processor, and channel estimation.

COFDM baseband processor on FPGA
2011 IEEE Second Latin American Symposium on Circuits and Systems (LASCAS), 2011This paper presents the design of a 12 Mb/s COFDM baseband processor compatible with the standard IEEE 802.11a. In this case, the architecture was described in VHDL, without use of IP cores or automatic generators, and the COFDM baseband processor with a cyclic prefix includes coarse and fine time synchronization system, and a channel coding system ...

Hierarchical transmission and COFDM systems
IEEE Transactions on Broadcasting, 1997Draft European terrestrial digital video broadcasting (DVB-T) standard will pose problems for in the selection of the most beneficial and cost effective modes of operation within this flexible standard. This paper describes possible implementations of coded orthogonal frequency division multiplexing (COFDM) transmission schemes.

A demapping method using the pilots in COFDM system
IEEE Transactions on Consumer Electronics, 1998This paper is concerned about the demapping method using the pilots inserted in transmitter in COFDM (coded orthogonal frequency division multiplexing) system which is the standard transmission system of terrestrial digital TV in Europe. We have tested the demapping method of this paper under the standard Rayleigh and Rician fading channel and obtained
