Multiple ARQ Processes for MIMO Systems
EURASIP Journal on Advances in Signal Processing, 2004 We propose a new automatic repeat request (ARQ) scheme for MIMO systems with multiple transmit and receive antennas. The substreams emitted from various transmit antennas encounter distinct propagation channels and thus have different error statistics ...

An Effective Go-Back-N Automatic-Repeat-Request Scheme for Variable-Error-Rate Channels
Radioengineering, 1999 In non stationary channels, error rates vary considerably. This paper proposes an effective go-back-N (GBN) Automatic-Repeat-Request (ARQ) scheme which estimates the channel state in a simple manner, and adaptively switches its operation mode.

Comparison of error control schemes in wireless sensor networks
Tongxin xuebao, 2008 Energy efficiency analyses of automatic repeat request （ARQ） and forward error correction （FEC） techniques were presented. Chase combining hybrid ARQ （HARQ） was proposed to achieve adaptive error control in wireless sensor networks.

A Comparison of Selected GBN ARQ Schemes for Variable-Error-Rate Channel Using QAM
Radioengineering, 2002 In non-stationary channels, error rates vary considerably. The papercompares Yao's Adaptive Go-back-N (GBN) Automatic-Repeat-Request (ARQ)scheme with Adaptive go-back-N with sliding window mechanism which bothestimate the channel state in a simple manner,

Analytical resource optimization for DF relay-assisted transmission under HARQ [PDF]
, 2009 Under limited channel state information at the transmitter the communication suffers from the outage events produced by a data rate selection not supported by the current channel realization. Automatic repeat request (ARQ) protocols are a useful tool to
