The goal of this section is to compare current situations regarding wireless communications in railway and road operations, i.e. Communication Based Train Control (CBTC) and Car to Infrastructure (C2I) communications.
Recently, cognitive radio (CR) provides great flexibility by extending software radio to improve spectrum utilization [2 6], which is now regarded as a hopeful wireless communication system.
Perhaps the most important aspects in the future of wireless communication and particularly regarding m-commerce are the creation, design, and control of wireless portals.
While at time slot t + 1, the distributed jamming beamforming weight is stacked in vector f d = [f d1, f d2, ⋯, f d(M − 1)] T. Regarding the available CSI in a wireless communication system, the receiver usually estimates the channel using a training sequence (pilot symbols).
This morning, Intel said it is setting up a research center in Sweden, generally regarded as the epicenter of the wireless communication world thanks to the presence of Ericsson ericy.
The E-UTRA is regarded as the preliminary version of next generation wireless communication system because of its capability to satisfy demand for higher user bit rates [1, 2].
Motivated by the ever increasing growth in multimedia applications and the number of users, millimeter wave (mmWave) has been regarded as an essential technique for the next generation wireless communication network [1].
Consequently, mobility support is widely regarded as one of the key features in current and future wireless communication systems.
To meet the explosive demand of proximity services, device-to-device (D2D) communication has been regarded as an ideal candidate technology for the next generation 5G wireless communication.
Moreover, the application of smart antenna (SA) technologies to OFDMA is regarded as a key solution for increasing the data rates and the mobility of fourth generation (4G) wireless communication systems operating in frequency-selective fading environments.
