Abstract
In this paper, we describe two different dipulse techniques both based on PRBS read-back wave forms. The first method, which requires computation in the discrete time Fourier transform domain, uses two different PRBS sequences with certain properties to obtain the phase and magnitude information. The second method is time domain correlation base and it requires the PRBS sequences the corresponding the readback waveform.
