An Experimental Comparison of Cross Correlator Performances Based Upon Signal-To-Noise RatiosGopani, Sunder G. 01 April 1981 (has links) (PDF)
Three commonly employed types of cross correlators were designed using standardized components which closely simulate idealized elements in an effort to experimentally verify the theoretical analysis. These cross correlators are (1) the standard analog cross correlator which consists of bandpass filters, a multiplier and a postmultiplier lowpass filter, (2) the polarity coincidence correlator (PCC) which utilizes a hard clipper in each input channel, and (3) a modified type of PCC which features a hard clipper in only one of the input channels. Two different types of filters viz. (1) the seventh-order Butterworth lowpass filter, and (2) the five-pole Chebyshev lowpass filter with a maximum passband loss of 1 dB were utilized. The output signal-to-noise ratio (SNR) was experimentally computed as a function of input signal-to-noise ration and compared with theoretical predictions. The performance in terms of output SNRs of the three cross correlators are compared. In all cases, the experimental results were in close agreement with the theoretical models.

Simulation of a binary phase shift keyed receiver with an IF correlator for position locationThommana, John Vareed 08 April 2009 (has links)
This thesis conducts a feasibility study of using a binary phase shift keyed receiver with an IF correlator in a position location application. The feasibility study is done using mathematical simulation. Traditionally the correlator, in a binary phase shift keyed receiver, is placed after the data demodulator. It correlates the incoming bitstream with a fixed reference bit sequence (synchronization header) to find the beginning of a data message. For position location applications this correlator is used to record the time of arrival of the signal at the receiver. These correlators can maintain the correlation peaks at best only to 1% of the bit period. At 4800 bits per second, this translates to an inherent range error of 625 meters. This thesis investigates the feasibility of using an additional correlator after the IF bandpass filter which will correlate the IF waveform sample by sample so as to maintain the correlation peaks to better than 1% of the bit period. / Master of Science
