In this paper, we concentrate on equalization algorithms for amplitude and phase-modulated (APM) signals in non-cooperative burst communication, and have designed a multi-modulus blind equalization algorithm based on cyclic iteration. The algorithm could achieve a faster and more effective blind equalization while just using the samples of the receiver. Proposed scheme has a lower complexity, better...
This paper proposes a new method using fractional autocorrelation and the Haar wavelet transform to estimate the parameters of phase code and linear frequency modulation combined signal. The combined signal is transformed into a linear frequency modulation signal using square method and its chirp rate is estimated by fractional autocorrelation firstly. Then, the initial frequency is estimated through...
This paper focuses on the modified Cramer-Rao bounds (MCRBs) related to estimating the parameters of a noisy hybrid modulated signal which combines the pseudo-random binary codes (PRBC) phase modulation and linear frequency modulation (LFM) and gives a theoretical performance for estimators. The parameters to be estimated of the PRBC-LFM signal include signal amplitude, carrier phase, carrier frequency,...
