Bit error rate performance of in-vivo radio channel using maximum likelihood sequence estimation
Mezher, Mohad; Ilyas, Muhammad; Bayat, Oğuz; Abbasi, Qammer H. (Institute of Electrical and Electronics Engineers Inc., 2020)In this paper we present the Bit Error Rate (BER) performance of equalizers using in-vivo channel response measured using Vector Network Analyzer (VNA). Including the use of a Bandwidth (BW) of 50 MHz in the simulations, ... -
Evaluation of ultra-wideband in vivo radio channel and its effects on system performance
İlyas, Muhammad; Uçan, Osman Nuri; Bayat, Oğuz; Nasir, Ali Arshad; Imran, Muhammad Ali; Alomainy, Akram; Abbasi, Qammer H. (Wiley, 2019)This paper presents bit-error-rate (BER) performance analysis and improvement using equalizers for an in vivo radio channel at ultra-wideband frequencies (3.1 GHz to 10.6 GHz). By conducting simulations using a bandwidth ... -
Experimental analysis of ultra wideband in vivo radio channel
İlyas, Muhammad; Bayat, Oğuz; Abbasi, Qammer H. (Ieee, 2018)In this paper, we present the experimental analysis of in vivo wireless channel response on Ultra-Wideband (UWB) with the frequencies between 3.1 - 10.6 GHz. The analysis proves the location dependent based characteristics ... -
Location dependent channel characteristics for implantable devices
Ilyas, Muhammad; Bayat, Oğuz; Uçan, Osman Nuri; Imran, Muhammad Ali; Abbasi, Qammer H. (Institute of Electrical and Electronics Engineers Inc., 2020)This paper presents an impact on an in-vivo channel with respect to the position of ex-vivo antenna placement and its location. The paper also shows how the location of the antenna is impacting the channel. Three different ... -
Mathematical modeling of ultra wideband in vivo radio channel
İlyas, Muhammad; Uçan, Osman Nuri; Bayat, Oğuz; Yang, Xiaodong; Abbasi, Qammer H. (Ieee-Inst Electrical Electronics Engineers Inc, 2018)This paper proposes a novel mathematical model for an in vivo radio channel at ultra-wideband frequencies (3.1-10.6 GHz), which can be used as a reference model for in vivo channel response without performing intensive ... -
Performance enhancement of safety message communication via designing dynamic power control mechanisms in vehicular ad hoc networks
Alabbas, Amjed Razzaq; Hassnawi, Layth A.; Ilyas, Muhammad; Pervaiz, Haris; Abbasi, Qammer H.; Bayat, Oğuz (Wiley, 2021)In vehicular ad hoc networks (VANETs), transmission power is a key factor in several performance measures, such as throughput, delay, and energy efficiency. Vehicle mobility in VANETs creates a highly dynamic topology that ... -
Ultra wideband in vivo channel modelling with respect to ex vivo antenna location
İlyas, Muhammad; Bayat, Oğuz; İmran, Muhammad Ali; Abbasi, Qammer H. (Ieee, 2019)This article presents mathematical channel modeling for in-vivo communication in terms of the change in the position of the ex-vivo antenna at ultra wideband frequencies. It is shown that the location dependent characteristics ...
