In short burst communication system, the position and the number of pilot symbols have a great effect on frequency estimation accuracy and estimation range based on time-domain correlation frequency estimation algorithm. So a frequency estimation algorithm having a higher frequency estimation accuracy based on the summation of the entire cross correlation is given, and its estimation variance is derived...
Considering low estimation accuracy and small synchronization range of carrier synchronization algorithms in low signal-to-noise ratio (SNR) for short burst communication systems, a joint pilot and iterative decoding soft-output carrier synchronization algorithm is proposed, which utilizes the time-domain correlation algorithm for coarse estimation and makes hard decision directly for systematic soft-information...
Considering low estimation accuracy and small synchronization range of carrier synchronization algorithms in low signal-to-noise ratio (SNR) for short burst communication systems, a joint time-domain correlation and code-aided carrier synchronization algorithm is proposed. Firstly, a frame structure in which the pilot symbols are separated with data symbols is used. Then, a new frequency estimation...
