Fast block LMS algorithm for interference cancellation in DVB-T based passive bistatic radar

In this paper, we propose to use the FBLMS (Fast Block Least Mean Square) algorithm for Direct Path and Zero-Doppler Multipath Interferences (DPI and ZDMI) cancellation in DVB-T (Digital Video Broadcasting Terrestrial) Passive Bistatic Radars (PBRs). Diverse adaptive techniques are considered in pas...

Summary:In this paper, we propose to use the FBLMS (Fast Block Least Mean Square) algorithm for Direct Path and Zero-Doppler Multipath Interferences (DPI and ZDMI) cancellation in DVB-T (Digital Video Broadcasting Terrestrial) Passive Bistatic Radars (PBRs). Diverse adaptive techniques are considered in passive radars' literature but most of them are computationally intensive when the DVB-T signal is used as an illuminator of opportunity, i.e., very high bandwidth. Using Fast Fourier Transform (FFT) for coefficient updating, the FBLMS algorithm shows a faster convergence rate, a shorter processing time and better CAF (Cross Ambiguity Function) results.
