On the Power Spectral Density of the GSM Signaling Scheme

In this paper, the Power Spectral Density of encoded Gaussian Minimum Shift Keying (GMSK) which is the Signaling Scheme of the Global System for Mobile Communication (GSM) is derived by a combined approach of the autocorrelation method and Markov Process. In the analysis, the Amplitude Modulated Pulse decomposition proposed by P. Laurent is employed to ease computation. Encoding of the message data utilizes Convolutional Code of rate1/2. Results are for both the uncoded and coded waveform comparing variation in power spread over a range of frequency

An evaluation of half-cut technique for microwave-photonic access-point antenna miniaturization

A microstrip-fed broadband printed monopole antenna covering 1.7 - 6.0 GHz is miniaturized using half-cut technique, and arranged in pair for uplink/downlink microwave-photonic access point. This paper discusses the effect of the miniaturization to S11 and radiation pattern of individual antenna, and also the best choice of antenna pair, ground-plane type, and total width of the access point
