Parameter estimation using quantized observations is of importance in many practical applications. Under a symmetric 1-bit setup, consisting of a zero-threshold hard-limiter, it is well known that the large sample performance loss for low signal-to-noise ratios (SNRs) is moderate (2/Π or -1.96dB). This makes low-complexity analog-to-digital converters (ADCs) with 1-bit resolution a promising solution for future wireless communications and signal processing devices. However, hardware…

Wireless Channel Estimation with Low-Complexity 1-bit ADC and Unknown Quantization Threshold

The estimation accuracy which can be obtained with receive data preprocessed by a hard-limiter with unknown quantization level is studied and the necessary condition for a vanishing loss due to missing offset knowledge at a receiver with $1-bit ADC is established.

One-Bit Quantization Design and Channel Estimation for Massive MIMO Systems

Simulation results show that the proposed adaptive and random quantization schemes presents a significant performance improvement over the conventional fixed quantization scheme that uses a fixed (typically zero) threshold.

It is shown that for time-of-arrival (TOA) estimation under any SNR level it is possible to obtain a low-complexity 1-bit receive system which features a smaller performance degradation then the classical low SNR hard-limiting loss of 2/π (−1.96 dB).

Generalized Bussgang LMMSE Channel Estimation for One-Bit Massive MIMO Systems

This paper first extends the conventional Bussgang linear minimum mean square error estimator to the general nonzero threshold case, and then studies the problem of one-bit quantization design, aiming at minimizing the mean squared error of the generalized BLMMSE estimator.

On Lower Bounds for Nonstandard Deterministic Estimation

The general approach introduced is exemplified, among other things, with a new look at the well-known Gaussian complex observation models and an analysis of the relative performance of the NSMLEs, as well as a comparison with the MLBs for a large class of estimation problems.

Lower bounds for non standard deterministic estimation

This paper proposes an embedding mechanism that allows to transpose all the known lowers bounds into modified lower bounds fitted with non-standard deterministic estimation, encompassing the modified Cramér-Rao/Bhattacharyya bounds and hybrid lower bounds.

Performance Analysis for Channel Estimation With 1-Bit ADC and Unknown Quantization Threshold

The accuracy that can be obtained with received data processed by a hard-limiter with unknown quantization level is studied by using asymptotically optimal channel estimation algorithms by employing analytic error expressions for different setups while modeling the offset as a nuisance parameter.



Signal Parameter Estimation Using 1-Bit Dithered Quantization

The problem of estimation of a parameter thetas of a signal s(x;thetas) corrupted by noise assuming that only 1-bit precision dithered quantized samples are available is considered and an estimate that does not require the knowledge of the dither signal and the noise distribution is proposed.

Bayesian Parameter Estimation Using Single-Bit Dithered Quantization

The Bayesian parameter estimation problem using a single-bit dithered quantizer is considered and bounds on the mean squared error are derived that hold for all dither strategies with strictly causal adaptive processing of the quantizer output sequence.

Capacity of communications channels with 1-bit quantization and oversampling at the receiver

This paper considers the Oversampling gain from an information-theoretic perspective by analyzing the channel capacity with 1-bit quantization and oversampling at the receiver for the particular case of AWGN channels.

Overdemodulation for High-Performance Receivers with Low-Resolution ADC

The design of the analog demodulator for receivers with low-resolution analog-to-digital converters (ADCs) is investigated and it is shown that this classical approach is suboptimal under an estimation and information theoretic perspective.

CRLB Based Optimal Noise Enhanced Parameter Estimation Using Quantized Observations

It is proven that optimal additive noise can be represented by a constant signal level, which means that randomization of additive signal levels is not needed for CRLB minimization.

The spectrum of clipped noise

The present report calculates in some detail the (intensity) spectrum to be expected for clipped (also called "limited") noise. Two cases are considered: (A), the clipping of an unmodulated noise

The state-of-the-art of ADCs is surveyed, including experimental converters and commercially available parts, and the distribution of resolution versus sampling rate provides insight into ADC performance limitations.

Bayesian Estimation in the Presence of Deterministic Nuisance Parameters—Part I: Performance Bounds

The proposed risk-unbiased bound (RUB) is proved to be asymptotically achieved by the MMSE estimator with maximum likelihood estimates for the nuisance parameters, while the existing CR-type bounds are not necessarily achievable.

Bayesian Estimation in the Presence of Deterministic Nuisance Parameters—Part II: Estimation Methods

This paper presents properties of asymptotic uniform mean- and risk-unbiasedness of some Bayesian estimators: 1) the minimum MSE (MMSE) or maximum a posteriori probability (MAP) estimators with maximum likelihood (ML) estimates substituting the deterministic parameters, and 2) joint MAP and ML estimator, named JMAP-ML.

It is shown that with short data records, JMAP-ML is often preferable to ML in terms of both bias and variance, and a general relation between a possible maximization algorithm for J MAP-ML and the well-known estimation-maximization (EM) algorithm is indicated.
