Latest Patents
One of Chang-Gang Zhang's latest patents is related to Walsh code management in a code division multiple access cellular wireless communication system. This invention provides a method of operation that manages Walsh codes to ensure sufficient availability, preventing call blocking and supporting additional hand-off operations. In the initial operating condition, the system services normal hand-off operations, allowing a maximum number of cells and sectors to participate. Each cell or sector uses a unique Walsh code for its forward link signals. When the number of available Walsh codes for new calls is reduced to meet or exceed a threshold, the number of participating cells and sectors is reduced accordingly. This innovative approach allows for the release or non-use of some Walsh codes, and when sufficient codes are available again, more cells and sectors can participate in hand-off operations.
