Introduction
The basic Frequency Modulation communications system has:
1) Transmitter, which is the sub-system that takes the information signal and processes it prior to transmission. The transmitter modulates the information onto a carrier signal and broadcasts it over the channel
2) Channel: The medium which transports the modulated signal to the receiver. In this project, LED will be connected to FM transmitter end. Signals then will be picked up by the Photo Detector diode right before the FM Receiver
3) ....etc

Multiple access (MA) schemes are used to simultaneously share available bandwidth in communication systems. In conventional MA applications a finite and contiguous amount of spectrum which is designated for a particular service is allocated to multiple users. Therefore, the use of designated radio spectrum is unconstrained and can be utilized in many ways to achieve maximum efficiency. Time division multiple access (TDMA), frequency division multiple access (FDMA), and code division multiple access (CDMA) are the three major MA techniques. In ....etc

Frequency modulation


The fi rst public broadcast radio services introduced in the 1920s were in
the long-wave (LW) and then medium-wave (MW) band, using amplitude
modulation (AM) and limited by the technology of the time. Historically,
long- and medium-wave AM broadcasting has used restricted bandwidth,
approximately 4 kHz, which allows intelligible speech but is not very good
for music broadcasting, since music signals are typically 14–20 kHz in bandwidth.
Amplitude modulatio ....etc

ABSTRACT
There is a need to select the 'first step up' modulation scheme for higher data rate frequency hopping systems. This is seen as one step in a longer journey where considerably higher data rates are used. In order to make this progression viable, the first step should be taken with a well proven modulation scheme. An ....etc

A Surveillance Robot with Hopping Capabilities for Home Security


Abstract —
Most traditional home robots have always had problems with stairs, doorsills and other
obstacles that humans cross with ease in cluttered indoor environments. This paper
presents the development and characterization of a surveillance robot with hopping
capabilities for home security. The proposed robot can leap over obstacles. It can also roll
freely on flat floors and change its directions by the two-wheeled differential drive
system. It adop ....etc
