In this paper, a fine carrier recovery algorithm is proposed to maintain the synchronization even in a severe Doppler shift for orthogonal frequency division multiplexing (OFDM) systems such as digital video broadcasting for handheld (DVB-H), DVB for terrestrial (DVB-T) and DVB-T2. The proposed algorithm estimates the frequency offset by utilizing correlation values in the received OFDM symbols by...
In this paper, a fine carrier recovery algorithm is proposed to maintain a good performance even with Doppler shifts for OFDM systems. It estimates the frequency offset by utilizing two correlation values for intentionally added positive and negative frequency offsets. Its performance is compared with conventional algorithms such as Beek and Moose algorithms.
In this paper, we consider out-of-band radiations caused by high sidelobes in orthogonal frequency division multiplexing (OFDM) system. Suppression of sidelobes in OFDM system allows higher spectral efficiency and less interference with existing legacy systems in OFDM based overlay system. We combine different sidelobe suppression techniques to suppress the sidelobes in OFDM system. The multiple-choice...
This paper presents the application of RFID (Radio Frequency Identification) to identify the viewer in IPTV (Internet Protocol Television). RFID reader developed connects serially with IPTV STB (Set-Top Box) for authentication of viewer and service verification by identifying viewer tag wirelessly.

This paper presents a decision directed blind adaptive algorithm for carrier phase offset recovery of 8-VSB. The algorithm achieves phase recovery by minimizing the quadrature leakage into the in-phase component and removes undesirable local minima, which occur in most blind algorithms, by configuring the reliable leakage estimation region.
