254Accesses Synonyms Channel acquisition;Massive MIMO;Pilot reuse;Pilot scheduling Definitions Pilot reuse refers to a pilot approach in wireless transmission where pilot signals adopted in the same cell can be non-orthogonal. Massive multiple-input multiple-output (MIMO) transmission employs a large num...
ASUS Zenbook S 14 is equipped with the latest Wi-Fi 7 for the very best wireless connections — up to 4.8x*14 faster than the previous Wi-Fi generation. Your laptop will automatically link to the strongest Wi-Fi signal, and use all the available bandwidth efficiently. And with support for...
The Vivobook S15 picks up where ASUS left off. The OLED screen is very well made... . The laptop is light and powerful enough to do what you need in the office, thanks to its Snapdragon X Plus chip. When it comes to connectivity, the Vivobook is very well equipped, with plenty of ...
Thus, the receiver sensitivity of coherent detection is highly dependent on the SOP of the incoming signal in the absence of a polarization controller. A coherent receiver with polarization-diverse architecture can be employed to solve this problem. The schematic of a phase- and polarization-diverse...
Since the communication channel is at the bottom of the physical layer in a wireless communication system, the received signal can be seriously affected by channel dynamics caused by distortions, such as fading, noise, and interference [1]. As a result, the performance of the wireless system wi...

The SUN 100 preferably uses orthogonal frequency division multiplexing (“OFDM”) for communication between the elements 102, 104, 106, and 108. OFDM is a signal modulation technique in which a number of closely spaced orthogonal subcarriers are used to carry data. The data is divided into seve...
