Designing Complementary Sequence Sets With Impulse Like Complementary Auto-Correlation Function
Surya Prakash Sankuru, Prabhu Babu · IEEE Communications Letters · 2020
In this letter, we address the problem of designing unit modulus complementary sequence set with impulse-like complementary auto-correlation function which has immense potential with applications in ultra wide-band (UWB) communication system, code-division multiple-access (CDMA) system and active sensing systems like MIMO RADAR and SONAR. We have formulated the design problem as the minimization of complementary peak side-lobe level and proposed a monotonic algorithm based on the majorization-minimization technique. Through numerical simulations, we show the construction of sequence sets (of different lengths) with impulse like complementary auto-correlation - which is first of its kind in the sequence design literature. We also discuss the computationally efficient implementation of the proposed algorithm via FFT, IFFT operations.
