چکیده

In this paper, we present a closed-form expression of a Bayesian Cramér-Rao lower bound for the estimation of a dynamical phase offset for a random BPSK sequence in an AWGN channel. The received symbols are disturbed by carrier phase offset which follows a Wiener model. Considering a received observation sequence, we provide a first analytical expression of the Bayesian CRB. Then, we derive an asymptote-based lower bound which provides an interesting alternative between accuracy and computational cost.

Analytic and Asymptotic Analysis of Bayesian Cramér-Rao Bound for Dynamical Phase Offset Estimation

In this paper, we present a closed-form expression of a Bayesian Cramér-Rao lower bound for the estimation of a dynamical phase offset in a non-data-aided BPSK transmitting context. This kind of bound is derived considering two different scenarios: a first expression is obtained in an off-line context and then, a second expression in an on-line context logically follows. The SNR-asymptotic expr...

Channel, Phase Noise, and Frequency Offset in OFDM Systems: Joint Estimation, Data Detec- tion, and Hybrid Cramér-Rao Lower Bound

Oscillator phase noise (PHN) and carrier frequency offset (CFO) can adversely impact the performance of orthogonal frequency division multiplexing (OFDM) systems since they can result in inter carrier interference and rotation of the signal constellation. In this paper, we propose an expectation conditional maximization (ECM) based algorithm for joint estimation of channel, PHN, and CFO in OFDM...

Phase Noise and Carrier Frequency Offset in OFDM systems: Joint Estimation and Hybrid Cramér-Rao Lower Bound

In this paper, a new iterative pilot-aided algorithm based on expectation conditional maximization (ECM) for joint estimation of Wiener phase noise (PHN) and carrier frequency offset (CFO) in orthogonal frequency division multiplexing (OFDM) systems is proposed. Next, a new expression for the hybrid Cramér-Rao lower bound (HCRB) for joint estimation of PHN and CFO in OFDM systems is derived. Nu...

Optimal Placement of Training Symbols for Frequency Acquisition: A Cramér-Rao Bound Approach

We consider the problem of training symbol placement for timing acquisition in band-limited, baudrate sampled systems with inter-symbol interference and frequency offset. The conventional approach is to place known symbols at the start of the transmitted packet and use these at the receiver to run a trained phase-locked loop. We introduce an additional degree of freedom by allowing arbitrary lo...

[hal-00447402, v1] On-line Hybrid Cram ́er-Rao bound for oversampled dynamical phase and frequency offset estimation

This paper deals with the on-line estimation of a dynamical carrier phase and a frequency offset in a digital receiver. We consider a Brownian phase evolution with a linear drift in a Data Aided scenario. The proposed study is relative to the use of an oversampled signal model after matched filtering, leading to a coloured reception noise and a non-stationary power signal. We derive a closed-fo...
