Two-stage-sparse algorithm for carrier Doppler-shift acquisition in space communications

Two-stage-sparse algorithm for carrier Doppler-shift acquisition in space communications

In space communications, the signal faces long-distance transmission and a high-dynamic relative movement. The long-distance transmission results in a very low signal-to-noise ratio (SNR) and the high-dynamic relative movement causes a high-dynamic Doppler-shift on the carrier. To address the low SN...
