“…It is preferable that TM^-the product of the bit duration times the signal bandwidth-be odd. The probability of error P^ is then equal to the probability that more than half the decisions will be in error and is given by the binomial distribution (TW-1)I2 /JXY\ TW-k (1) where P^ is the probability of error for any one sample. Jacobs [1] has plotted PE as a function of TW^l -P^y for various values of TW.…”

In this paper we determine P^ on the understanding that the error probability with postdetection integration can then be calculated from (1) or by using the plots given by Jacobs. Since P^ is a monotonic function of P^, the conclusions reached in this paper concerning the helpfulness of limiting with single-sample detection also apply with postdetection integration.…”

Abstract-This paper considers the problem of the detection of a binary phase-modulated carrier which has been transmitted along with noise through a hard-limiting repeater, corrupted by additional noise, and demodulated by cross correlation and sampling at the receiver. Three equivalent expressions are obtained for the error probability of the receiver output. Two of these expressions take the form of an infinite series involving either confluent hypergeometric functions or modified Bessel functions. A third form allows representation of the error probability in terms of Rice's le function. In the special case where the signalto-noise ratios Pi^ and p2^ at the limiter and receiver inputs are equal, the error probability is simply Pe = iexp i-pi^).Asymptotic expressions for the error probability for large and small signal-to-noise ratios are also derived. The error probability is found to be smaller than that of a linear system for all practical values of limiter and receiver input signal-to-noise ratios. The optimum repeater nonlinearity is investigated and is shown to be a limiter at such signal-to-noise ratios.

“…Second, overcoming the nonlinearity caused by a fully saturated power amplifier helps to combat the nonlinearity introduced by power amplifiers operated with some linearity such as class-B and class-C. Fully saturated power amplifiers cause severe nonlinearity to nonconstant envelope signals [4][5][6][7]. If a system can utilize fully saturated power amplifiers, the system performance will become better when linear power amplifiers are employed.…”

“…As data rates become much higher in broadband wireless and satellite networks, a user terminal has to transmit at higher power levels than in the existing wireless communication systems [1][2][3]. To reach the required high transmission power and high power efficiency, power amplifiers working in the fully saturated region must be employed [4][5][6][7]. However, they often cause severe nonlinear distortion to the signal.…”

Abstract-This paper studies the performance of ultra-wideband (UWB) radio communications systems employing phase shift keying (PSK) modulation and fully saturated power amplifiers through additive white Gaussian noise (AWGN) channel or Rayleigh fading channel. An impulse response method is provided to analyze the signal-to-noise ratio (SNR) degradation. Both convolutional code and turbo code are employed with the Viterbi decoding and the iterative decoding, respectively. The decoding algorithms are modified for the Rayleigh fading channel. Near optimal bit error rate (BER) performance is achieved when employing either convolutional code or turbo code. The simulation results match the derivation. Therefore, fully saturated power amplifiers can be employed in UWB PSK systems to significantly reduce radio cost, simplify radio circuit, and increase battery life for portable terminals.Index Terms-Bit error rate (BER), fading channel, modulation, nonlinear radio channel, ultra-wideband (UWB).
