Abstract Error correcting codes can play a key role in improving the efficiency and reliability of wireless communications. Concatenated codes have the advantages that: 1) breaking the task into stages simplifies decoding, and 2) performance is good against clustered bit errors, fading and bursty interference. Reed-Solomon codes (maximum distance codes) have been popular as an outer code of con...

based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. in the present research, 2d molecular dynamics simulations have been used to investigate such behaviors. performing the planar simulations can provide a ...

the present study addresses the influence of iran’s post-revolution political structure on the formation of the country’s translated literature system. it examines the translated anglo-american novels pub-lished under two administrations in power after the islamic revolution: 1) the reformist administra-tion, which was a more liberal, leftist administration, seeking to improve iran’s relations ...

it has been reported previously that modulatory effects of pleasant and unpleasant slides on the human acoustic reflex are observed only if startle probes are presented to the left ear or with binaural presentation. the present study examined the effects of the left and the right ear stimulation on modulated startle reflex (as indexed by eyeblink component, measured at the right eye) employing ...

Subband Adaptive Orthogonal Frequency Division Multiplexing (OFDM) constitutes an effective method of compensating for the frequency selective fading incurred by mobile receivers. The channel transfer function estimation error increases both as a function of the Doppler frequency and that of the subband modem mode signalling delay. This leads to a degradation of the system’s performance. In thi...

this paper aims to discuss the requirements of safe and smooth trajectory planning of transporter mobile robots to perform non-prehensile object manipulation task. in non-prehensile approach, the robot and the object must keep their grasp-less contact during manipulation task. to this end, dynamic grasp concept is employed for a box manipulation task and corresponding conditions are obtained an...

In this paper, symbol-by-symbol maximum likelihood (ML) detection is proposed for a cooperative diffusionbased molecular communication (MC) system. In this system, a fusion center (FC) chooses the transmitter (TX) symbol that is more likely, given the likelihood of its observations from multiple receivers (RXs), where the TX sends a common information symbol to all RXs. The transmission of a se...

The processing complexity of optimal receivers in frequency selective channels grows exponentially with the channel memory length. Linear receivers, alternatively, offer significantly less complexity with the cost of performance degradation. Such degradation can be due to not fully capturing the inherent frequency diversity or degraded coding gain. In this paper we investigate how effectively t...

Symbol-by-symbol maximum a posteriori (MAP) decoding algorithms for linear nonbinary block and convolutional codes over both extension elds GF(q = p a) and integer rings Z q are presented. Equivalent MAP decoding rules employing the dual code are given which are computationally more eecient for high-rate codes. The suitabil-ity of the proposed algorithms is demonstrated by applying them to a pa...
