| Abstract: |
| A fast alg
orithm for blind detection of satellite signal is proposed in this paper. The al
gorithm
can not only detect signals accurately, but also easily obtain medium-frequency
signal parameters such as signal counts, bandwidth and carrier frequency u
nder great contrast of amplitude between signals. The algorithm is efficient and
needs fewer data
, and suits the satellite-borne equipment. Theoretical analysis and simulation r
esult
s confirm its availability. |
