Latest Patents

Reddy holds a patent for a "Method and system for maximum likelihood clock and carrier recovery in a direct sequence spread spectrum communication system." This invention provides a comprehensive method for clock and carrier recovery in such communication systems. The process involves the receiver receiving a digital signal transmitted by a remote transmitter. The method includes down-converting the received signal and converting it to digital form. The signal is then de-spread to obtain the phase of the signal constellation. The clock error at the receiver is estimated from the phase error of the signal constellation using an optimal linear estimator. Additionally, the discrete carrier frequency offset of the received signal is estimated from the estimated clock error. The optimal linear estimator used for estimating the clock error is also the maximum likelihood estimator.
