We determine the optimal adaptive rate and power control strategies to maximize the total
throughput in a multirate code-division multiple-access system. The total throughput of the …

Assuming there are always sufficient data waiting to be transmitted, adaptive modulation
and coding (AMC) at the physical layer have been traditionally designed separately from …

Adaptive modulation requires channel state information (CSI) at both transmitter and
receiver. In practice, CSI can be acquired at the receiver by inserting pilot symbols in the …

Adaptive coded modulation (ACM) is a promising tool for transmission in a fading
environment. The main motivation for employing ACM schemes is to improve the spectral …

Channel state information (CSI) at the transmitter can be used to adapt transmission rate or
antenna gains in multi-antenna systems. However, the CSI that is fed back will get outdated …

We develop a cross-layer design which combines adaptive modulation and coding (AMC) at
the physical layer with a truncated automatic repeat request (ARQ) protocol at the data link …

A performance analysis of an adaptive modulation (ACM) system operating on a multiple-
input multiple-output (MIMO) channel with uncorrelated Rayleigh fading subchannels is …

We examine a two-rate communication system where the transmission is suspended if the
received SNR falls below a given threshold. We assume an FDD system and derive novel …

We develop an adaptive time-diversity system equipped with adaptive modulation and
retransmissions over Nakagami-m block fading channels. Our scheme maximizes the …

Adaptive modulation improves system throughput considerably by matching transmitter
parameters to time-varying wireless fading channels. Crucial to adaptive modulation is the …
