Powerful and generic data-aided (DA) parameter estimators are necessary to accommodate many modes. In this paper, we present an approximated maximum likelihood (ML) carrier frequency offset estimator and their systolic VLSI implementations for PSK burst modems. The performances are close to the Cramer-Rao lower bounds (CRLB) as low SNRs. Compared with theoretical solutions the estimators proposed here are much simpler and easier to implement by the current VLSI technology. The CRLB for DA estimations is discussed in some depth, some issues on training sequence design are also addressed in the work.~},

	abstract = {A high-performance universal modem ASIC that supports several modulation types and burst mode frame formats are under development. The ASIC is designed to work under stringent conditions such as large carrier frequency offset (up to 13\% symbol rate) and low signal-to-noise ratio (SNR). Powerful and generic data-aided parameter estimators are necessary to accommodate many modes. In this paper, we present an approximated maximum likelihood (ML) carrier frequency offset estimator, ML joint carrier phase, and timing offsets estimator and their systolic VLSI implementations for PSK burst modems. The performances are close to the Cramer-Rao lower bounds at low SNRs. Compared with theoretical solutions the estimators proposed here are much simpler and easier to implement by the current VLSI technology.},

	abstract = {A high-performance ASIC supporting multiple modulation, error correction, and frame formats is under development at Hughes Network Systems, Inc. Powerful and generic data-aided (DA) estimators are needed to accommodate operation in the required modes. A simplified DA maximum likelihood (ML) joint estimator for carrier phase and symbol timing offset for QPSK/OQPSK burst modems and a sample systolic VLSI implementation for the estimator are presented. Furthermore, the Cramer-Rao lower bound (CRLB) for DA case is investigated. The performance of the estimator is shown through simulation to meet the CRLB even at low signal-to-noise ratios (SNR). Compared with theoretical solutions, the proposed estimator is less computationally intensive and is, therefore, easier to implement using current VLSI technology},

	abstract = {In this paper we present an autocorrelation-based method for estimating the carrier frequency offset of an MPSK signal with random data modulation. Although autocorrelation based techniques imply heavy usage of hardware resourses this technique is scalable and lends itself to systolic VLSI implementations. The performance of the open-loop estimator presented is close to Cramer-Rao lower bound (CRLB) for the frequency estimation from a block of random MPSK symbols at low signal-to-noise ratios (SNR). The estimator can be used in frequency acquisition of burst and continuous modems operating under low SNR and large frequency offset conditions.},
