Cyclic Prefix And Precursor Joint Estimation
US Patent:
2013014, Jun 13, 2013
Filed:
Dec 13, 2011
Appl. No.:
13/324225
Inventors:
Amit Ranjan Dubey - Los Angeles CA, US
Cimarron Mittelsteadt - Santa Clarita CA, US
Cimarron Mittelsteadt - Santa Clarita CA, US
International Classification:
H04B 1/10
US Classification:
375346
Abstract:
A method of operating a communications system includes generating a channel impulse response estimate based on a first received signal. The method includes selecting a precursor and a cyclic prefix length for a second received signal based on the channel impulse response estimate, a target cyclic prefix energy level, and a predetermined range of cyclic prefix lengths.
Coarse Timing Acquisition
US Patent:
2013014, Jun 13, 2013
Filed:
Dec 13, 2011
Appl. No.:
13/324217
Inventors:
Amit Ranjan Dubey - Los Angeles CA, US
Cimarron Mittelsteadt - Santa Clarita CA, US
Cimarron Mittelsteadt - Santa Clarita CA, US
International Classification:
H04L 27/06
US Classification:
375343
Abstract:
A coarse timing acquisition technique includes generating a sequence detection indicator. The sequence detection indicator indicates detection of a sequence of repeated symbols in a received signal. The sequence detection indicator is based on a first energy threshold and a normalized moving sum of an autocorrelation signal. The autocorrelation signal is based on the received signal.
