- W2350843584 abstract "In order to solve the conflict between scarcity of the spectrum resources and the urgent demand for high capacity digital communication systems,the bandwidth efficiency of the digital communication systems should be high.In this paper,a new band-pass digital modulation technologies-1/2Continous phase Chirp Keying(1/2-CPCK),whose energy is highly concentrated,are analyzed.The segmented Chirp signals serve as the waveform samples of modulated signals,which make use of the features that frequency between modulated signals transmits smoothly to improve bandwidth efficiency.The paper introduces the mathematical models of 1/2-CPCK and its power spectral density,the energy concentration of modulated signals is analyzed.The BER of the 1/2-CPCK digital communication system is analyzed by simulation.Theoretical analysis and simulation results show that the energy and bandwidth efficiency of 1/2-CPCK are high,1/2-CPCK digital communication system has better adaptation to additive white Gaussian noise channel." @default.
