Channel state information (CSI) at the transmitter can be used to adapt transmission rate or
antenna gains in multi-antenna systems. We propose a rate-adaptive M-QAM scheme …

In this paper, performance of a rate-adaptive multiple-input multiple-output diversity system
with imperfect channel state information is analyzed and optimized. Space-time block coding …

Unifying and generalizing the works of Cai and Giannakis and Oien et al., the performance
of an adaptive trellis-coded modulation system where receive antenna diversity is …

In this paper, we present a new adaptation scheme for MIMO systems using linear
dispersion code. The statistics of signal-to-interference-noise for a MIMO transceiver using …

Channel state information (CSI) at the transmitter can be used to adapt transmission rate or
antenna gains to time-varying fading channels in multi-antenna systems. However, the CSI …

The design of spectrally efficient and robust schemes is vital to overcome the harsh wireless
environment when delivering high data rate services. In the present paper, the performance …

For high speed wireless systems adopting adaptive modulation, we compare the achievable
performance of adaptive beamforming (A-BF) and adaptive orthogonal space time block …

This work presents an adaptive spatial multiplexing scheme for time‐varying correlated
multiple‐input multiple‐output (MIMO) channels. Unlike the conventional spatially …

The thesis is largely built on a collection of published and submitted papers where the main
focus is to analyze and optimize single-carrier adaptive coded modulation systems with and …

Since the capabilities of MIMO systems were discovered, much research effort has been
invested in this field. However, in most applications, the channel state information (CSI) is …
