Sentence examples for projection orders from inspiring English sources

What's more important is that, both the PAPA and the MPAPA algorithms require a M×M direct matrix inversion, which is especially expensive for high projection orders.

Meanwhile, the memory of the filter's coefficients were exploited to improve the performance and further reduce the complexity for high projection orders.

The affine projection order was selected as M=2.

However, this drawback could be mitigated through increasing the projection order.

The convergence and the tracking become faster when the projection order increases.

Furthermore, the memory of the filter's coefficients will also improve the performance as the projection order increases.

However, the simulation results will demonstrate that this approximation works pretty well, especially for relatively high projection order.

However, it is known that if the projection order increases, the convergence speed is faster, but the steady-state error also increases.

This was caused by the relatively low projection order (M=2), and the implementation of the MRAP was slower than the direct matrix inversion.

Meanwhile, a sliding-window recursive least squares (SRLS) low-cost implementation of PAPA is given based on DCD, which does not depend on M. The SRLS implementation is only efficient when the projection order is very high (e.g., such as M=512) [19].

Butterworth filtered-back projection (order = 7, cutoff = 0.45 cycles/cm) was used for image reconstruction and attenuation correction was performed using Chang's method (attenuation coefficient = 0.11/cm).
