In this paper, the average achievable rate and error probability of a reconfigurable intelligent surface (RIS) aided systems is investigated for finite blocklength (FBL) regime. The performance loss due to presence phase errors arising from limited quantization levels as well hardware impairments at RIS elements also discussed. First, composite channel containing direct path plus product reflec...

Rate-Splitting Multiple Access (RSMA) is an emerging flexible and powerful multiple access for downlink multi-antenna networks. In this paper, we introduce the concept of RSMA into short-packet communications. We design optimal linear precoders that maximize sum rate with Finite Blocklength (FBL) constraints. The relations between blocklength are investigated a wide range network loads user dep...

113 INTRODUCTION The growing demand from the commercial and military sectors for on-the-move communications at high data rates has generated interest in a new type of satellite terminal. These terminals can provide broadband communications from maritime vessels, trains, airplanes, land vehicles, and other transportation systems. Although the interest in the commercial sector is primarily in bro...

background  short stature is a manifestation of a wide variety of conditions that some of which may be amenable to timely treatment and a suboptimal growth rate may be an early marker pointing to the cause of growth retardation. this study was conducted to evaluate the diagnostic utility of growth rate in differential diagnosis of children with short stature. materials and methods all children ...

Ultra-Wideband (UWB) was approved by the Federal Communications Commission (FCC) in Mar. 2002 for unlicensed operation in the 3.1-10.6 GHz band subject to modified Part 15 rules. The rule limits the emitted power spectral density (p.s.d) from a UWB source measured in a 1 MHz bandwidth at the output of an isotropic transmit antenna at a reference distance to that shown in Figure 1. Further, the ...

The ability to monitor multiple sources of concurrent auditory information is an integral component of Navy watchstanding operations. However, this leads to attentionally demanding environments. The present study tested the utility of a potential solution to listening to multiple speech communications in an auditory display environment: presenting speech serially at synthetically accelerated ra...

The need for critical improvements to the North American surface transportation infrastructure vis-a-vis alleviation of congestion while enhancing public safety has led to new intelligent transportation system (ITS) infrastructure based on vehicle-to-vehicle (v2v) wireless communications. The allocation of 75 MHz in the 5.9 GHz band for dedicated short-range communications (DSRC) may also enabl...

Ultra-wideband (UWB) radio is a promising technology for low-cost, high-rate communications at short ranges. However, high bandwidth and low power of the UWB signals impose some difficult challenges in signal processing and implementation of the receiver. Acquisition of the signal timing is the first task to be performed in a coherent receiver. The high bandwidth of UWB signals demand for fine ...

Through the history and since 1933, the Iranian rial has declined from 11.2 rials per dollar to almost 8600 rials per dollar today in the parallel or black market. At the same time the official rate has been kept at artificial level most of the time, not consistent with other macro conditions of the country. Historically, however, the Central bank has adjusted the official rate and brought it i...
