An adaptive hidden Markov model approach to FM and M-ary DPSK demodulation in noisy fading channels
In this paper extended Kalman filtering (EKF) and hidden Markov model (H M M) signal processing techniques are coupled in order to demodulate frequency modulated signals in noisy fading channels. The demodulation scheme presented is applied to both digital A4-ary differential phase shift keyed (M DPSK) and analog frequency modulated (FM) signals. Adaptive state-and-parameter estimation schemes ...
متن کاملLow latency IIR digital filter design by using metaheuristic optimization algorithms
Filters are particularly important class of LTI systems. Digital filters have great impact on modern signal processing due to their programmability, reusability, and capacity to reduce noise to a satisfactory level. From the past few decades, IIR digital filter design is an important research field. Design of an IIR digital filter with desired specifications leads to a no convex optimization pr...
متن کاملAnalysis of Spectral Notching in FM Noise Radar Using Measured Interference
It was recently shown that spectral notches can be incorporated into a physically realizable form of FM noise radar. Here it is shown how these spectral notches can be used to permit radar operation in a band where narrowband interference sources are present. The impact of interference and associated notches in different regions of the waveform spectrum (i.e. passband versus roll-off regions) i...
متن کاملA Very Low Voltage 9th Order Linear Phase Baseband Switched Capacitor Filter (RESEARCH NOTE)
A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...
متن کاملA Low-Rate Wireless Spread-Spectrum Communication Technique using Linear Step FM Signal
A low data-rate communication technique using linear step frequency modulated (LSFM) signal is presented. When the carrier frequency offset (CFO) between the transmitter and the receiver is significant comparing to the symbol rate, the techniques using normal signaling waveforms with matched filtering become infeasible. In this scenario, wideband chirp (linear FM) signal is feasible because of ...
