20090303972 | Dynamic Scrambling Techniques for Reducing Killer Packets in a Wireless Network - Techniques are disclosed in which a parameter used for scrambling packet data is changed.

In a network that employs frequency-hopping spread spectrum communications, a channel identifier can be employed as an input to the scrambling algorithm. In this implementation, a given packet of data will be transmitted on one channel with a first sequence of bits when it is scrambled, and on another channel with a different sequence of bits. If the scrambled packet for one of these channels results in a killer packet, it is statistically unlikely that it will also be a killer packet when it is re-transmitted on the other channel. | 2009-12-10 |

The system is used in the uplink or the downlink of a cordless or wireless TDMA system. When there are unused data slots available, the system allocates redundant slots in a data frame to a single mobile unit. The receiving device calculates a quality of slot (QoS) score for each slot that it receives data for. After the QoS score is calculated, the system calculates a Quality of Audio Segment (QoAS) score for each individual segment. It does so by comparing the individual audio segments that were received. Segments that are identical are assigned a positive score, while segments that differ get no score. The QoAS for each segment is added to the QoS for the slot the segment was transmitted in to generate the total score. The system then chooses the segment with the highest total score. If the total score is above a specified threshold, the system outputs the segment to the next component. Otherwise, it outputs a mute segment. | 2009-12-10 |
