Challenges in wireless communication for connected sensors and wearable devices employed in sport training program applications

Sensors, wearables, wireless networks, and alternative web of Things technologies are ever a lot of gift in our standard of living. we have a tendency to study their pertinency and use in training program systems and applications in sport. training program systems are necessary in motor learning wherever someone within the loop uses the feedback info to influence the execution performance. Sensors, actuators, and wireless technologies are available nice varieties relating to their properties. we have a tendency to describe the foremost common teams of sensors and actuators that are employed in sport and list the most widespread and simply offered wireless technologies. we have a tendency to gift the foremost necessary constraints of a training program system operation and outline variety of elementary architectures of biofeedback systems. Taking into consideration all of the higher than, we have a tendency to gift variety of various training program application situations in sports. we have a tendency to match the situations to the foremost acceptable existing wireless technology that’s expected to sustain measurability within the range of nodes or enhanced information rates for the expected application period of time. we discover out that presently none of the present wireless technologies will satisfy the range of demands of various training program application situations.

Dual-Polarization FBMC for Improved Performance in Wireless Communication Systems

Filter bank multi-carrier (FBMC) offers superior spectral properties compared to cyclic-prefix orthogonal frequency-division multiplexing (CP-OFDM), at the price of associate degree inherent disadvantage in dispersive channels referred to as intrinsic notional interference. during this paper, we have a tendency to propose a replacement FBMC-based communication system victimisation 2 orthogonal polarizations for wireless communication systems: dual-polarization FBMC (DP-FBMC). victimisation this method we will considerably suppress the FBMC intrinsic interference. so in DP-FBMC all the multicarrier techniques employed in CP-OFDM systems like channel deed, etc., ought to be applicable while not victimisation the complicated process strategies needed for typical FBMC. DP-FBMC conjointly has alternative fascinating blessings over CP-OFDM and FBMC: it’s a lot of strong in extremely dispersive channels, and conjointly to receiver carrier frequency offset and temporal order offset. In our DP-FBMC system we have a tendency to propose 3 totally different structures supported different multiplexing techniques. we have a tendency to show that compared to traditional FBMC, one amongst these DP-FBMC structures has equivalent quality and instrumentality necessities. we have a tendency to compare DP-FBMC with alternative systems through simulations. in keeping with our results DP-FBMC has potential as a promising candidate for future wireless communication networks.

Clipping Noise and Power Allocation for OFDM-Based Optical Wireless Communication victimization gauge boson Detection

The clipping noise of the photon-level detector for each direct current-biased optical OFDM and unsymmetrically clipped optical OFDM is investigated. supported Bussgang theorem and central limit theorem, we have a tendency to get the approximate closed-form SNR of every subcarrier, supported that we have a tendency to additional formulate the facility allocation among the subcarriers. Numerical results show that the SNR obtained from theoretical analysis will well approximate that obtained from simulation results, and uniform power allocation suffices to perform near the optimized power allocation from genetic algorithmic rule with considerably reduced procedure complexness.

Brain-inspired methods to improve wireless communications

Researchers are forever seeking additional reliable and more economical communications, for everything from televisions and cellphones to satellites and medical devices.

One technique generating buzz for its high signal quality may be a combination of multiple-input multiple-output techniques with orthogonal frequency division multiplexing. [4]

An Overview of call Techniques for Vertical football play Across Wireless Heterogeneous Networks

Future wireless communication networks popularly called on the far side third generation (B3G) or Fourth generation (4G) networks will possible include heterogeneous wireless networks which can be IP-Centric primarily based. These networks can supply a good vary of high information transmission services to mobile users. to realize this, Vertical football play (VHO) is taken into account because the technique of realization and it’s outlined as the method by that users can seamlessly tramp amongst these heterogeneous networks whereas act. to understand VHO, effective and economical algorithms for correct VHO call are of utmost importance and therefore kind a part of current analysis focus. during this regards, many efforts are created and it’s the particular objective of this paper to produce an summary of efforts made up to now whereas discussing connected VHO ideas. Specifically, football play sorts, football play method and classification of vertical handoff, metrics needed, and existing works are given. we have a tendency to request to produce a aphoristic background for not simply VHO call algorithms however additionally for understanding the fundamental idea of VHO.
