Source bearing and steering-vector estimation using partially calibrated arrays [PDF]
, 2009 The problem of source direction-of-arrival (DOA) estimation using a sensor array is addressed, where some of the sensors are perfectly calibrated, while others are uncalibrated. An algorithm is proposed for estimating the source directions in addition to

Minimum Bit Error Rate Assisted QPSK for Pre-FFT Beamforming in LTE OFDM Communication Systems [PDF]
Jordanian Journal of Computers and Information Technology, 2016 In this paper, a diamond shape pilot arrangement for OFDM channel estimation is investigated. Such arrangement will decrease the number of pilots transmitted over the communication channel which in turn will increase data throughput while maintaining ...

Massive MIMO Channel Estimation With Low-Resolution Spatial Sigma-Delta ADCs
IEEE Access, 2021 We consider channel estimation for an uplink massive multiple-input multiple-output (MIMO) system where the base station (BS) uses an array with low-resolution (1-2 bit) analog-to-digital converters and a spatial Sigma-Delta ( $\Sigma \Delta ...

OCEANS 82, 1982 A description of a method for the determination of array shape is given in three dimensions using measurements of array heading and depth taken at known points along the array, including the mathematical basis for the method. The applicability of this procedure to the determination of array shape is based on the idealization of the array, containing ...

Array Processing and Fast Optimization Algorithms for Distorted Circular Contour Retrieval
EURASIP Journal on Advances in Signal Processing, 2007 A specific formalism for virtual signal generation permits to transpose an image processing problem to an array processing problem. The existing method for straight-line characterization relies on the estimation of orientations and offsets of expected ...
