Noise problems in pulse communication

Rectangular-Wave Modulation

“…Jelonek's formula gives results 1-1/2 dB higher than the experimentally obtained values [5]. The same difference is found in the present experimental results.…”

“…Andrews [3] and Miller and Lee [41 have considered the pdf of the analog correlator output. Wilson [5] and Andrews and Brice [61 have considered the pdf and cumulative distribution function (cdf) of the sum of analog correlator output samples. …”

Interference Characteristics of Pulse-Time Modulation

“…Before studying the distributions of the sinusoid and rectified sinusoid, it should be pointed out that the Gaussian distribution of time shifts is that actually obtained as a result of random noise, so that the power spectrum The two most important probability distributions as far as the interference characteristics of PTM are concerned are those derived and discussed in Chapter 2 and defined by (12) and (14), respectively. Again, the evaluation of (50) cannot be performed analytically, and the two plots in Fig.…”
