| 1996 | Design of wideband all-digital phase locked loops using multirate digital filter banksabstractAll-digital phase locked loops (DPLLs) have many advantages over analog loops. However, due to digital device limitations and costs, superwide PLLs with front-end bandwidths as high as one gigahertz are commonly implemented using analog parts. This article presents a new architecture that allows an all-digital implementation of superwide PLLs. The problem of operating digital components at high speed is avoided here (without reducing the front-end bandwidths) by inserting a multirate digital filter bank in front of the DPLL. The new design is shown to have steady-state and transient performance that is identical to a conventional DPLL. Ramin Sadr, Biren Shah, Sami Hinedi |

| 1989 | Degradation of signal-to-noise ratio due to amplitude distortionabstractThe effect of filtering on the signal-to-noise ratio (SNR) of a coherently demodulated band-limited signal is determined in the presence of worst-case amplitude ripple. The problem is formulated as an optimization in the Hilbert space L/sub 2/. The form of the worst-case amplitude ripple is specified, and the degradation in the SNR is derived in closed form. It is shown that, when the maximum passband amplitude ripple is 2 delta (peak-to-peak), the SNR is degraded by at most (1- delta /sup 2/), even when the ripple is unknown or uncompensated. For example, an SNR loss of less than 0.01 dB due to amplitude ripple can be assured by keeping the amplitude ripple under 0.42 dB.> Ramin Sadr, Mehrdad Shahshahani, William J. Hurd |

| 1988 | Generalized minimum shift-keying modulation techniquesabstractThe simultaneous data demodulation and phase tracking of an MSK signal using the Viterbi algorithm is described, and two variations of MSK modulation are studied. The MSK with overlay is a dual-rate modulation techniques in which low-rate and high-rate data are superimposed on an MSK signal. Here the demodulator uses the Viterbi algorithm to estimate both the low-rate and high-rate data simultaneously. The MSK with pseudorandom sequence spreading combats intentional or unintentional jamming. A simplified receiver for these spread-spectrum MSK signals is found that takes into consideration the effect of random phase perturbations. The performance of these demodulators is evaluated using transfer-function bounds for the bit error probability. For demodulation of the spread spectrum MSK signal, a simplified receiver is derived, and its performance in the presence of continuous jamming is evaluated.> Ramin Sadr, Jim K. Omura |
