％The phase locked loop(PLL),adjusts the phase of a local oscillator
％w.r.t the incoming modulated signal.In this way,the phase of the
％incoming signal is locked and the signal is demodulated.This scheme

demodulates the FM modulated signal Y at the carrier frequency Fc (Hz). Y and Fc have sample frequency Fs (Hz).
FREQDEV is the frequency deviation (Hz) of the modulated signal.

he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a constant period. The current value of this signal at a certain poiTnt of time is proportional to its Duty Cycle. That s the High Time during one perio ...

Obtain the CDF plots of PAPR from an OFDM BPSK transmission specified per IEEE 802.11a specification
Per the IEEE 802.11a specifications, we 52 have used subcarriers. Given so, the theoretical maximum expected PAPR is 52 (around 17dB). However, thanks to the scrambler, all the subcarriers in an OFDM ...

uses the message signal X to modulate the carrier frequency Fc (Hz) and sample frequency Fs (Hz), where Fs >
2*Fc. FREQDEV (Hz) is the frequency deviation of the modulated signal.

This Simulink model simulates as an example the transmission and reception of random digital data modulated with GMSK. The purpose of this model is to illustrate how part of the GSM transmission and reception works. It also measures the BER, affected by an AWGN channel.

This is a paper describing Pulse Compression technique implemented in the Weather Radar system. This paper presents data examples from the
radars and contrasts the use of pulse compression
waveforms with more traditional non-modulated
pulsed waveforms.
