After describing the basic concepts and technical features of single-carrier and multi-carrier systems, this paper analyzes and compares the performances of the two schemes against Doppler spread, Multi-path spread and Error propagation in DTTB mobile reception environment.

The development of the Digital Television Terrestrial Broadcasting (DTTB) and channel characters of the DTTB are first described in this paper,and the channel estimation method for the DMB-T (Terrestrial Digital Multimedia/Television Broadcasting) standard innovated by Digital TV R&D Center of Tsinghua University is then discussed in details.

Hardware implementation of inner coding and inner interleaving at the transmitter end of terrestrial digital video broadcasting(DVB-T) are introduced.

An FPGA design and implementation of a pipelining channel outer decoder is introduced in detail in this paper, which can be applied not only in DVB-T receiver but also in DVB-S and DVB-C receivers.

After the effort of several years,Chinese national standard on digital television terrestrial broadcasting system has reached a mature and eventually released.

Based on the method of proper comparison of system carrier noise ratio performances used by Yiyan WU et al, and prototype test results, it is shown in this paper that the performances of the Chinese transmission standard of digital television terrestrial broadcasting(C-std) is better than ATSC or DVB-T.

Analysis on LDPC Decoding Algorithm of Chinese DTTB system;

With the background of the National Standard for DTTB, we propose a time-domain adaptive cancellation method which is achieved by analyzing the PN sequence in the received TDS-OFDM signal to obtain an estimation of the impulse response of the coupling channel, and then using the estimation result to generate a feedback signal to cancel the echo.
