"According to the U.S. National Highway Traffic Safety Administration, single-vehicle road departures result in many serious accidents each year. To reduce the likelihood of a vehicle's straying out of lane, automotive engineers have developed lane tracking and departure warning systems that use a small camera to transmit video information about lane markings and road conditions to a microprocessor unit installed on the vehicle.

The MATLAB program simulates binary frequency shift keying (BFSK) at baseband through Monte Carlo method. The goal is to simulate bit error rate (BER) over an additive white Gaussian noise (AWGN) channel. For realizing that, the effect of noise is represented in the baseband with Gaussian random samples added to each signal sample.

Some curve fitting or smoothing tools can benefit from knowledge of the noise variance to expect on your data. Kalman filters use this information, also some spline fitting tools. So I wrote a function to extract the noise variance from a signal vector.

function y = getiq(x,freq) this takes in the frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q - this is used when you have frequency X changing and the phase is cumulative - meaning it does not start each new frequency at the same spot OR function y = getiq(data,freq,fc) this takes in frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q based around a center frequency FC this is used when you have frequency X changing and the phase is cumulative - meaning it does not start each new frequency at the same spot.
