A method for determining distances and relative velocities of objects with using a radar includes transmitting a ramp-like frequency-modulated transmission signal whose modulation pattern includes multiple sequences of ramps having an identical ramp slope, which alternately follow each other, the sequence...
The P-SyS in E-UTRAN are based on Zadoff-Chu (ZC) sequences, which are a special class of generalized chirp-like (GCL) sequences. A ZC sequence having a length N, where N is odd, and a sequence index u is defined by the following expression: ...
While there has been a plenty of studies on the interference of frequency modulated continuous wave (FMCW) radars, no work on chirp sequence (CS) radars has been reported in the literature in spite of their growing popularity in the automotive field. In this regard, this work presents an ...
This paper deals with a new method to design polyphase spreading sequences for DS CDMA wireless applications. The method is based on weighting symbols of the orthogonal Walsh sequences by the complex factors being symbols of baseband chirp sequences. The resulting sequences possess good aperiodic ...
