Latest Patents

One of his latest patents is titled "Data multiplexing for diversity operation." This invention focuses on a satellite mobile telecommunications system that utilizes the GSM standard and a TDMA frame structure. It employs discontinuous transmission (DTX) mode to capitalize on the silences that occur during normal speech. In this mode, traffic channel (TCH) data is not transmitted, but control of the link between a ground station and a user terminal is maintained by sending control channel data bursts (SACCH) along with silence descriptor (SID) frames. To manage transmission power effectively, the emission time of the bursts is controlled to ensure uniformity over available sending opportunities. This approach is particularly innovative as conventional techniques cannot be applied in systems that include diversity operation.

Another significant patent is "Neighboring cell list generation in a mobile satellite communication system." This invention describes a mobile communication system comprising multiple satellites and mobile stations. A mobile station can communicate with more than one satellite, and a satellite transmits a set of neighboring cell data to the mobile station. The data set includes portions related to communication with different satellites. Upon receiving this data, the mobile station decodes both portions to establish a neighboring cell list, which is stored for future reference. This efficient method allows the mobile station to decode only the necessary data in subsequent transmissions, enhancing communication efficiency.
