| 内容記述 | Effects of Doppler shift and data modulation taken into account. Two advanced schemes for acquisition of direct-sequence spread-spectrum codes proposed. M1-Lag correlator in each strip of spread-spectrum-code detector operates at different offset code-chip time. Each offset represents assumed (tentative) Doppler shift. Schemes have highly parallel architecture implemented with currently available technology. Possible to use hybrid parallel/serial architecture in which acquisition time varies in inverse proportion to number of correlators and fast-Fourier-transform processors. |
