Joint Activity Detection and Channel Estimation for Massive Random Access Using SBL and SCA
Esa Ollila, Majdoddin Esfandiari, Daniel P. Palomar
In massive machine-type communication (mMTC) applications, a key challenge is joint device activity detection and channel estimation (JADCE) under grant-free random access, as a ma…
AdaBoost-Based Efficient Channel Estimation and Data Detection in One-Bit Massive MIMO
Majdoddin Esfandiari, Sergiy A. Vorobyov, Robert W. Heath
The use of one-bit analog-to-digital converter (ADC) has been considered as a viable alternative to high resolution counterparts in realizing and commercializing massive multiple-i…
DOA Estimation in Nonuniform Sensor Noise
Majdoddin Esfandiari, Sergiy A. Vorobyov
The problem of direction-of-arrival (DOA) estimation in the presence of nonuniform sensor noise is considered and a novel algorithm is developed. The algorithm consists of three ph…
Non-Iterative Subspace-Based DOA Estimation in the Presence of Nonuniform Noise
M. Esfandiari, S. A. Vorobyov, S. Aliban +1
The uniform white noise assumption is one of the basic assumptions in most of the existing directional-of-arrival (DOA) estimation methods. In many applications, however, the non-u…
