| 发明名称 | Time-alignment of signals suffering from quadrature errors | ||
| 摘要 | Data is received characterizing a first signal and a second signal. The first signal and a function of the second signal is compared at a plurality of time-shifts to estimate a time-difference between the first signal and the second signal. The function of the second signal includes the second signal, a complex conjugate of the second signal, and a constant. The comparison is provided. At least one of receiving, comparing, and providing is performed by at least one processor of at least one computing system. | ||

| 主权项 | 1. A computer-implemented method, comprising: receiving data characterizing a first signal and a second signal; comparing, at a plurality of time-shifts, the first signal and a function of the second signal to estimate a time-difference between the first signal and the second signal, the function of the second signal including a linear combination of the second signal, a complex conjugate of the second signal, and a constant, the linear combination chosen for each of the plurality of time shifts to minimize the estimate at a given one of the plurality of time shifts and such that the linear combination varies between two or more of the plurality of time shifts; and providing the comparison; wherein at least one of the receiving, the comparing, and the providing is performed by at least one processor of at least one computing system. | ||
