The Reliability Function of Arbitrary Channels With and Without Feedback
نویسنده
چکیده
The reliability function of arbitrary single-user communication channels is analyzed. A general formula for the partitioning upper bound to the reliability function of channels without feedback is rst established. This bound is indeed a consequence of the recently derived general expression for the Neyman-Pearson type-II error exponent subject to an exponential bound on the type-I error probability. A general lower bound to the non-feedback channel reliability function is also obtained using Feinstein's Lemma. Finally, the above bounds are extended to arbitrary channels with feedback.

An approximate model for slug flow heat transfer in channels of arbitrary cross section
In this paper, a novel approximate solution to determine the Nusselt number for thermally developed, slug (low-prandtl), laminar, single phase flow in channels of arbitrary cross section is presented. Using the Saint-Venant principle in torsion of beams, it is shown that the thermally developed Nusselt number for low-prandtl flow is only a function of the geometrical parameters of the channel c...

Background and Aim: This study aimed to evaluate the effects of scapular-focused treatment with (SFTF) and without (SFT) feedback on pain, function, and scapular kinematics in patients with Shoulder Impingement Syndrome (SIS). Materials and Methods: 36 males and females with SIS (age of 37 ± 6.3 years) were randomly assigned into SFTF (n=12), SFT (n=12) and control (n=12) groups. The primary o...
متن کاملBounds for Multiple-Access Relay Channels with Feedback via Two-way Relay Channel
In this study, we introduce a new two-way relay channel and obtain an inner bound and an outer bound for the discrete and memoryless multiple access relay channels with receiver-source feedback via two-way relay channel in which end nodes exchange signals by a relay node. And we extend these results to the Gaussian case. By numerical computing, we show that our inner bound is the same with o...
متن کاملOn The Reliability Function of Discrete Memoryless Multiple-Access Channel with Feedback
We derive a lower and upper bound on the reliability function of discrete memoryless multiple-access channel (MAC) with noiseless feedback and variable-length codes (VLCs). The bounds are similar to the one for point-to-point channels, increasing linearly with respect to an appropriate distance between the rate pair and the capacity boundary. For the lower bound on the error exponent, we adapt ...
متن کاملVariable-length codes for channels with memory and feedback: error-exponent upper bounds
The reliability function of memoryless channels with noiseless feedback and variable-length coding has been found to be a linear function of the average rate in the classic work of Burnashev. In this work we consider unifilar channels with noiseless feedback and study upper bounds for the channel reliability function with variable length codes. In unifilar channels the channel state is known to...
