Diversity,dern wireless communications, the concept has been further expanded to use multiple antennas at both the transmitter and receiver, referred to as multiinput multioutput (MIMO). The basic concept of diversity is that if we have multiple channels of information, then the chances of all of the channels

Multicarrier, data rate and number of users has also increased. This is true for all wireless standards except AMPS (1G) which was a pure analog system with 30 kHz bandwidth and voice-only transmission. GSM (2G) which was the first digital system allowed for voice and SMS to be sent. Both these standards, AMPS a

Shannon Capacity,annon gave his theory known as “A Mathematical Theory of Communication” which formed the basis of the field of Information Theory. He postulated that whatever the source of information, a human voice, a piece of music, or a text document, must first be converted into bits for efficient transmission

Phase and Frequency, are multiple signals spaced closely in the frequency domain. Some of the methods that we discuss in this chapter are Zero Crossing Detector, Kay’s estimator, FFT, MUSIC, and ESPRIT. The first two methods are quite accurate and easy to implement, but they work only for a single sinusoid embedded in

Simulation in Python,own up using MATLAB for their design and simulation tasks. We have become so comfortable with it that we now even think in terms of vectors and matrices. We apply an averaging filter all the time in our daily life, taking out the inherent randomness.
