When multiplying numbers in the complex plane, the angle of the two are added allowing us to easily correct every sample. Now we see why complex numbers are useful. The corrected IQ samples are shown below.127 After finding the frequency offset and phase, we can multiply each IQ sample by some exponential e^(-''i''*<delta>)^ where <delta> stands in for the error / angle offset of that sample.
