To achieve reliable packet transmission over a wireless link without feedback, we propose a
layered coding approach that uses error-correction coding within each packet and erasure …

Optimization of the switching thresholds for constant-power adaptive five-mode M-ary
quadrature amplitude modulation (M-QAM) transmission with an amplify-and-forward (AF) …

We consider the problem of quality of service (QoS) routing in multi-hop wireless networks
where data are transmitted from a source node to a destination node via multiple hops. The …

Cross-layer optimization solutions have been proposed in recent years to improve the
performance of wireless users that operate in a time-varying, error-prone network …

The use of constant-power, rate-adaptive M-QAM transmission with an amplify-and-forward
cooperative system is proposed. The upper bound expressions are derived for the outage …

The performance analysis of multi-input-multi-output (MIMO) systems with M-ary quadrature
amplitude modulation (MQAM) and a space-time block code (STBC) over flat Rayleigh …

In this paper, we present a cross-layer approach for video transmission in wireless LANs that
employs joint source and application-layer channel coding, together with rate adaptation at …

In this paper, we study the performance of a channel-adaptive packet transmission system
over fading channels with a finite transmit buffer. This transmission scheme combines the …

In this paper, we consider an incremental relaying protocol based on an amplify-and-forward
transmission in conjunction with a best relay selection scheme over non-identically …

In general, link-adaptive schemes, such as adaptive modulation and coding (AMC) and
hybrid automatic repeat request (HARQ), enhance system capacity in time-varying wireless …
