Latest Patents

One of his latest patents is titled "System and apparatus for designing and producing signalling waveforms for direct-sequence code division multiple access communications." This invention focuses on identifying direct sequence CDMA pulse shapes that optimize a cost function under various constraints. The cost function can be either an acquisition signal-to-noise ratio (SNR) or interference power. The method is applicable to both full-response and partial-response pulse shapes, with constraints including a quasi-constant envelope, continuous phase, spectral nulls, and intersymbol interference (ISI) free conditions. The Fourier transform of the desired pulse shape is expressed as a finite sum of prolate spheroidal wave functions, and numerical methods software is utilized to determine the optimal solution.

Another significant patent is the "Multilevel distributed frame selection and power control CDMA architecture method and apparatus for telecommunication networks." This invention describes a mobile communications system featuring a multi-level distributed frame selection and power control architecture. It includes multiple base station transceiver subsystems (BTSs) arranged in cells, each capable of establishing a radio frequency interface with subscriber units during telephone calls. The system implements power control and frame selection of compressed packet data, enhancing the efficiency of mobile communications.
