Latest Patents

One of Arikan's latest patents is a "System and method for CDMA communications." This innovation presents a system and method for spread spectrum communication, primarily designed for mobile CDMA communication systems. The system receiver features a simplified architecture, which includes a channel compensator and correlation detector. The channel compensator is equipped with a channel estimator and signal constructor. In a preferred embodiment, the channel estimator periodically computes the cross-ambiguity function of the transmitted and received pilot signals of the CDMA system using computationally efficient processing algorithms. The signal constructor utilizes the estimated multipath parameters to create a new signal, significantly mitigating the effects of the multipath channel.

Another significant patent is the "System and method for detection and tracking of targets." This system employs fractional Fourier transformation of time-domain signals to compute projections of the auto and cross ambiguity functions along arbitrary line segments. The efficient computational algorithms in this embodiment are utilized to detect the position and estimate the velocity of signals, which can be encountered by active or passive sensor systems. Various applications of the proposed algorithm in the analysis of time-frequency domain signals are also disclosed.
