Comparison of the required number of multiplications and additions for the GPS SDR for CRPA in this paper and a conventional GPS L1(C/A) SDR. N is the number of inphase or quadrature samples per millisecond (NL5 = 10 NL1). NL5 = 20,000 is used in this work.
| GPS SDR for four-element CRPA | Conventional GPS SDR | |
|---|---|---|
| Carrier and code wipeoff | 1,080 NL5 | 216 NL1 |
| Data synthesis by weighting | 360 NL5 | N/A |
| Covariance calculation | 64 NL5 | N/A |
