Latest Patents
Ramesh's latest patents include two key innovations. The first patent focuses on the estimation of sample clock frequency offset based on error vector magnitude. This invention outlines a system and method for operating a receiver to estimate the offset between the actual sample clock rate and the intended sample clock rate. The receiver captures samples of a received baseband signal and operates on these samples to generate an estimate for the clock rate offset. The resampled data represents an estimate of the baseband symbols transmitted by the transmitter. The process involves computing an error vector signal and estimating the clock rate offset using this signal, with variations depending on the presence of carrier frequency and phase offsets.
The second patent also addresses the use of error vector magnitude to estimate sample clock frequency offset. Similar to the first, it describes a low complexity system for operating a receiver to estimate the clock rate offset. The receiver captures samples at a specific rate and processes them to generate an estimate for the clock rate offset, which is then used to resample the captured data. This innovation further enhances the accuracy of baseband symbol estimation.
