In [1], Chandar et al studied a problem of sequential frame synchronization for a frame transmitted randomly and Uniformly in an interval of size A slots. For a discrete memoryless channel, they showed that the frame length N must scale as e > A for the frame detection error to go to zero (asymptotically with A). α(Q) is defined as the synchronization threshold for the discrete memory-less chan...

The present paper is the second part of a previously published overview entitled “ten years of severe plastic deformation (SPD) in Iran”. Part I concentrates on the equal channel angular pressing (ECAP). In this part, the focus is on the accumulative roll bonding (ARB) because, currently, Iran is ranked the first in the world by the total number of publications in this field. In the present sec...

in biaxially strained p-mosfet with si channel, formation of a parasitic parallel channel due to misalignment of energy bands degrades device performance by increasing off-state current. in this paper a new approach has been introduced to eliminate this parasitic channel by increasing the dopant concentration of virtual substrate up to . using simulation the impact of this method on the parasit...

zinc is a substance that regulates neural excitability by binding whit sodium channel and potassium channel. the efficiency of free zinc ion, make down the neural survival rate, reduced the peak amplitude of na+ and make depolarization na channel, increased the peak amplitude of transition outward k+ currents and delayed rectifier. also it is an effective blocker of one subtype of tetrodoxine (...

The physical layer security (PLS) performance of a wireless communication link through large reflecting surface (LRS) with phase errors is analyzed. Leveraging recent results that express the LRS-based composite channel as an equivalent scalar fading channel, we show eavesdropper's Rayleigh distributed and independent legitimate link. different scaling laws eavesdroppers signal-to-noise ratios ...

We investigate the composite effects of multipacket reception (MPR) and relaying capability in affecting the stability region of a wireless network. With a general MPR channel, a trade-off arises as to whether to activate the relay simultaneously with the source so that both transmissions might be successful, or to let the relay remain silent to overhear the source’s transmission and then activ...

| We focus on the design of multiuser receiver structures for Code Division Multiple Access (CDMA) communication systems, in the presence of multipath e ects and multiple sensors at the base station receiver. We present a exible and extensible framework that allows the use of an estimated e ective spreading code from the channel estimation phase, in the multiuser detection process. The effectiv...
