The encoded data, which is in orthogonal space, modulates the laser beam by means of O 3 K. At the receiver, two photocells are cross coupled to compensate for the sunlight and other atmospheric noise. Since the laser beam is highly directional and can only be acquired by one photocell, the input laser signal can then be received with little noise, and signal processing is made easier. These techniques are especially beneficial in high bandwidth, long distance secure laser communication applications, such as for use in unmanned aerial vehicles.

To meet growth requirements, it is often required to adopt reuse schemes with smaller reuse distances, and this in turn results in modification of the existing frequency plan. The proposed frequency transition scheme allows for gradual expansion, smooth transition and

In the proposed technique, the input digital signal is mapped into a block of orthogonal code. The encoded data, which is in orthogonal space, modulates the laser beam by means of On-Off Keying. At the receive side, the data is recovered by means of code correlation. This modulation technique offers

The instrument is based on Electron Spin Resonance and Fresnel Zone break point. It is shown that an unknown sample, placed between the transmit and the received antenna,, separated by a distance less than the Freznel Zone break point, absorbs electromagnetic energy at

It is based on dividing all the available channels into 9 or multiples of 9 groups. The basic N=9 cell cluster uses an ODD/EVEN channel distribution scheme which forms a 3 × 3 array of nine frequency groups. The

Both forward and reverse control channels (FOCC & RECC) are examined in the presence of interference and Rayleigh fading and prediction equations are developed. It is shown that the control channel capacity is a function of carrier-interference ratio and Rayleigh fading.

devices, the wireless data traffic is growing exponentially.
As a result, the network spectral efficiency saturates despite new
standards and great technological advancements. By 2015, it is
expected that total wireless data traffic will reach 6 exabytes per
month, creating a 97% gap between the traffic demand per device
and the available data rate per device. In addition, it is estimated
that by 2017 more than 11 exabytes of data traffic will have
to be transferred through mobile networks every month. Most
recently, Visible light communication (VLC) has been identified
as a potential solution for the emerging RF spectrum crisis.
Light Fidelity (Li-Fi), first introduced by Harald Haas, uses Light
Emitting Diode (LED) for visible light spectrum for high-speed
data communication, shows very promising results. The concept
of combining the functions of illumination and communication
offers the potential for tremendous cost savings and carbon
footprint reductions.
In this paper, we will compare the different optical modulation
techniques which can be used in the emerging Li-Fi system, which
is a full networking solution for mobile communication using
VLC.
