Latest Patents

One of Yang's latest patents focuses on a multi-carrier and multi-rate CDMA system. In this innovative system, a base station transmits an index tag to multiple mobile stations. The index tag has a length that indicates a transmission rate, and all index tags are organized as nodes in a code tree. Within this code tree, mother nodes and their child nodes block each other, ensuring they are not assigned to mobile stations simultaneously. Additionally, index tags of nodes at the same level of the code tree are orthogonal to one another. The mobile station constructs an index tag matrix based on the index tag, which is then multiplied with a generating matrix stored in each mobile station. This process generates a spreading factor matrix, with rows corresponding to different carriers.
