Automatic mob sensor timing adjustment
When reading calibration chevrons during mark-on-belt (MOB) sensor timing calibration, cyan portions or legs of printed chevrons are detected in order to determine a timing window offset adjustment. Depending on which of the six cyan legs on the left side of the chevrons are detected, a determination can be made regarding whether the window needs to be started earlier or later. If only the first two cyan legs on the left side of the chevron are detected, then the MOB sensor timing window is beginning (and ending) too early and an appropriate adjustment can be made to cause the timing window to initiate later. If only the last two cyan legs on the left side of the chevron are detected, then the MOB sensor timing window is beginning (and ending) too late, and appropriate adjustment can be made to cause the timing window to initiate earlier. |

Transmit beamforming with singular value decomposition and pre-minimum mean square error
Transmitting beamforming can steer a transmitting signal to reduce the interference between spaces of a MIMO system and achieves constructive combination at the receiver. One method of steering matrix calculation includes using singular value decomposition (SVD). Notably, the singular values of SVD, which represent the stream strengths in a MIMO system, are in descending order. In equal modulation, signal strength degradation makes the receive EVM of the latest stream poor and increases the probability of packet error. MMSE can be used to weight the steering vectors of the steering matrix calculated in SVD. This weighting of the singular values can balance the SNR of the streams, thereby improving packet error rate. |
