Optimal SNR Exponent of MIMO-ARQ Block-Fading Channels
In this report, we consider an automatic-repeat-request (ARQ) retransmission protocol signaling over a blockfading multiple-input, multiple-output (MIMO) channel. Unlike previous work, we allow for multiple fading blocks within each transmission (ARQ round), and we constrain the transmitter to fixed rate codes constructed over complex signal constellations. In particular, we examine the general...
متن کاملPerformance of Hybrid ARQ Schemes over Multipath Block Fading Channels
The use of Hybrid Automatic Repeat reQuest (HARQ) for error correction has been given wide attention in the High Speed Downlink Packets Access (HSDPA) mode of the UMTS (3GPP TR 25.848 2001). This paper derives a theoretical analysis of the performance of Automatic Repeat reQuest (ARQ) and Type I Hybrid ARQ (HARQ I) over a block multipath Rayleigh fading channel. It is shown that the derived ana...
متن کاملPerformance of ARQ Go-Back-N Protocol in Markov Channels With Unreliable Feedback
In this paper, an ARQ Go-Back-N protocol with time-out mechanism is studied. Transmissions on both the forward and the reverse channels are assumed to be subject to Markovian errors. A recently developed approach, based on renewal theory, is further extended and the steady state average number of packets in the ARQ system is evaluated. This allows us to determine analytically both throughput an...
متن کاملOn adaptive go-back-N ARQ protocol for variable-error rate channels
This letter presents a simple method to simultaneously optimize a multiplicity of design parameters for the adaptive automatic repeat request strategy previously reported, and subsequently provides a quantitative measurement that reflects the appropriateness of the selected parameters. An exact analytical expression that allows us to compute the throughput crossover probability between the two ...
متن کاملAn effective go-back-N ARQ scheme for variable-error-rate channels
RQ (AUTOMATIC-REPEAT-REQUEST) techniques, A including stop-and-wait, go-back-N, and selective repeat, are widely used for error control in data communication systems. Particularly, the go-back-N ARQ scheme is very popular because it provides higher throughput compared to stop-and-wait ARQ, and its implementation is simpler than selective repeat ARQ since it does not require buffering and resequ...
