Application Of Classical Cosine Series Window Functions To Full Response Signaling Offset Quadrature Binary Modulation Systems

Abstract

Classical cosine series window functions have been applied to the synthesis of finite impulse response filters because of their closed analytic form and low sidelobe levels. It is proposed that classical cosine series window functions be applied to finite symbol duration quadrature binary modulation systems as pulse shapes in the interest of increasing the spectral confinement of the resulting modulated signals. The respective modulation systems are analyzed in terms of modulated signal envelope uniformity, spectral confinement and bit error rate in the presence of white Gaussian noise with varying degrees of modulated signal amplitude compression. It is observed that even in the presence of moderate modulated signal compression, classical cosine series window function pulse shapes offer equal or better spectral confinement for quadrature binary modulation systems than the conventional pulse shapes corresponding to QPSK, MSK, SFSK, and DSFSK. It is also shown that moderate levels of modulated signal compression have negligible effects on the system bit error rate. A system implementation using the sum of FSK modulated signal components to achieve spectral confinement based on the classical cosine series window functions is presented. © 1993 IEEE
