Vehicular Ad-hoc Networks (VANETs) is a wireless networking technology that can be used to support the emergence of Intelligent Transportation Systems (ITS). The deployment of these systems will allow connected vehicle to communicate each other and also with the road side infrastructures in order to avoid possible accidents and provide more comfort applications to the driver and passenger. The designers...
Massive MIMO technology can increase capacity, data rate, and link reliability significantly without additional bandwidth or transmission power. Most of the previous study on Massive MIMO systems are using low frequency (2.6 GHz). This frequency is not suitable for future broadband technology, because IoT devices will use high frequency and possible cell coverage would be smaller. This work proposes...
A time domain signal tracking algorithm is proposed to estimate the frequency of a chirp-type global navigation satellite system (GNSS) interference. The unknown interference frequency of GNSS in the received signal can be estimated by using the properties of the trigonometrical functions, but the thus-obtained value can have a lot of error caused by measurement noise and by the frequency change of...
The increasing demand for data usage drives the efforts for higher throughput in telecom and data networks. Having higher throughput helps users to save time. Evidences from existing operators also demonstrate that when subscribers experience higher throughput, their data usage increases which provides a recurring revenue boost. Operators not only enhance user experience and revenue, they also make...
Phased Multiple-Input Multiple-Output (PMIMO) radar which uses overlapped noncoherent transmit subarrays and noncoherent receive arrays provide better performance in transmit-receive gain and SINR than Phased Array and MIMO radar. This paper shows PMIMO approach which uses a coherent receive array provides the same performance as other radars but is more efficient in its use of matched filters and...
In the uplink system, different carrier frequency offsets (CFO) of different users at the receiver resulting multiuser interference (MUI) and thus degrade the performance of Multicarrier Code Division Multiple Access (MC-CDMA) system. In the previous study, Modified Minimum Mean Square Error Frequency Domain Equalization (Modified MMSE-FDE) has been proposed by Agnihotri which results in a better...
