Abstract

The purpose of the present study is to reduce the high Peak-to-Average Power Ratio (PAPR) in Digital Beam-Forming (DBF). We propose a method based on conformal transformation and compressive sensing (CS). We make a sparse array manifold, following that sampling the DBF signal compressively. Then we clip and filter the sampled signal in the analytic domain which is gotten through the conformal transformation. Reconstructing the previous signal could be accomplished through CS. Compared with the former ways, the test experiment results show that by the presented method, the operation speed is faster; the out-band noise and the in-band jamming are much lower.

Key words
