| Title | OFDM Frame structure and channel Estimation Technique for digital television terrestrial broadcasting system |
| Abstract | Orthogonal frequency division multiplexing (OFDM) is the most popular technology to transmit data in many wireless communication applications including digital television terrestrial broadcasting (DTTB). Over fast fading channels, iterative padding subtraction (IPS) based time domain synchronous OFDM (TDS-OFDM) has good spectral efficiency, but at a cost of high computational complexity. Dual pseudo noise padding (DPNP) based TDS-OFDM is used to reduce the computational complexity compared to IPS-based TDS-OFDM by compromising with spectral efficiency. An alternate time-frequencydomain (TFD) based frame structure enhances the system performance of TDS-OFDM over fast time-varying channel at a cost of high computational complexity. |
