Many-antenna MU-MIMO faces a critical, previously unaddressed challenge: it lacks a
practical control channel. At the heart of this challenge is that the potential range of MU …

Certain optimization problems in communication systems, such as limited-feedback constant-
envelope beamforming or noncoherent M-ary phase-shift keying (MPSK) sequence …

A Finite Feedback Scheme (FFS) for a quasi-static MIMO block fading channel with finite N-
ary delay-free noise-free feedback consists of N Space-Time Block Codes (STBCs) at the …

In this paper, we consider transmit beamforming (BF) design under per-antenna power
constraint (PPC) for multiple-input-single-output (MISO) frequency-selective channels. Both …

The performance of beamforming versus space‐time coding using a body‐worn textile
antenna array is experimentally evaluated for an indoor environment, where a walking …

Multiuser—Multi carrier systems like MU-MIMO-OFDM Systems has been widely known for
offering maximum spatial diversity along with maximum spectral efficiency which is of high …

With the advance in Computer-Aided Design (CAD) technology, digital design in VLSI has
moved from the bottom-up design approach to top-down design methodology with the aid of …

The aim of this thesis is to study the design of closed-loop multiple antenna aided wireless
communications relying on limited feedback. Multiple antennas may be employed …

Digital communication is emerging day by day with the fast internet and networking
technology. There are recent trends and technology such as 4G and then 5G working in …

In this paper, we investigate limited feedback precoding for two single-user MIMO systems.
The first one employs spatial diversity at the transmitter and Maximum Ratio Combining at …
