In the past as well as present wireless communication systems, the wireless propagation
environment is regarded as an uncontrollable black box that impairs the received signal …

Integrated sensing and communication (ISAC) has the advantages of efficient spectrum
utilization and low hardware cost. It is promising to be implemented in the fifth-generation …

The book systematically introduces theories of frequently-used modern signal processing
methods and technologies, and focuses discussions on stochastic signal, parameter …

Optimally extracting the advantages available from reconfigurable intelligent surfaces (RISs)
in wireless communications systems requires estimation of the channels to and from the RIS …

Tensors or multiway arrays are functions of three or more indices (i, j, k,...)-similar to matrices
(two-way arrays), which are functions of two indices (r, c) for (row, column). Tensors have a …

An approach to the general problem of signal parameter estimation is described. The
algorithm differs from its predecessor in that a total least-squares rather than a standard …

The theory of compressed sensing suggests that successful inversion of an image of the
physical world (broadly defined to include speech signals, radar/sonar returns, vibration …

The performance of the MUSIC and ML methods is studied, and their statistical efficiency is
analyzed. The Cramer-Rao bound (CRB) for the estimation problems is derived, and some …

A study of a matrix pencil method for estimating frequencies and damping factors of
exponentially damped and/or undamped sinusoids in noise is presented. Comparison of this …

Array processing involves manipulation of signals induced on various antenna elements. Its
capabilities of steering nulls to reduce cochannel interferences and pointing independent …
