  • Abstract
    An improved signal quality estimation algorithm applicable to CDMA-based mobile communication systems, is proposed. The algorithm estimates the Eb/N0 at the receiver end by operating on the despread symbols of the received in-phase (I) and quadrature (Q) channels. The improvement in performance is obtained by the addition of a smoothing filter to the existing algorithm. The performance of the algorithm is compared initially in a Gaussian channel and then in a time-varying channel that emulates fast fading
