This paper presents a channel estimation (CE) method for transmit diversity systems based on time-domain synchronous orthogonal frequency division multiplexing (TDS-OFDM) scheme. Compared with conventional methods, the proposed CE method doesn't need the hypothesis that the channel responses over two consecutive signal frames or over two adjacent subcarriers are equal. Thus, it can greatly improve...
Compared with the global positioning system (GPS), the digital television (DTV) broadcasting signal is a promising candidate for position location due to low implementation cost and strong signal reception. Without changing the current infrastructure of the Chinese DTV broadcasting network, this paper proposes a novel positioning scheme using the multi-carrier pseudo-noise (PN-MC) training sequence...
Digital television/terrestrial multimedia broadcasting (DTMB), announced as the Chinese digital television terrestrial broadcasting (DTTB) standard, uses pseudo-noise (PN) sequence as guard interval (GI) and the training sequence for both multi- and single-carrier block transmissions. The conventional channel estimation methods can be performed through either the subtraction of the PN sequence or...
