Title: Edwin A Kelley: Innovator in Digital Receiver Technology
Introduction
Edwin A Kelley is a notable inventor based in Los Angeles, CA, with a significant contribution to the field of digital receiver technology. He holds a total of 12 patents, showcasing his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Multiple user digital receiver apparatus and method with time division." This invention is designed for multiple simultaneous users and digitizes a received analog RF signal. It tunes to multiple desired frequencies of the received signal on a time division multiplexed basis. After filtering by a finite impulse response (FIR) filter that operates in time division multiplexing for multiple service bands, the selected signals are digitally demodulated and processed on a time-shared basis. Different service bands are accommodated simultaneously by separate FIR filters, each with a coefficient memory for its specific service band. The multiplexed frequency signal for each band is multiplied by the coefficients of its respective FIR filter memory in a common complex multiplier. The results are then demultiplexed and directed to respective accumulators for decimation according to the FIR coefficient characteristics.
