Latest Patents

The key patent held by David Hertz is for an "Asynchronous CDMA decorrelating detector." This method and apparatus solve the challenge of optimally decoding messages from a CDMA signal sent by multiple users and received asynchronously at a single receiver. What sets Hertz's invention apart is its ability to operate using minimal computations and memory resources. The method employs a unique approach to signal correlation and a subsequent decoding process that requires only a correlation period of one symbol length.

The core of Hertz's invention is the use of a pair of partial signature sequences for each user, enabling efficient correlation of the signal. This results in the de-correlation of outcomes through the inverse of the cross-correlation matrix of all partial sequences. Ultimately, this innovative method yields accurate final estimated symbol values by combining the resultant partial symbol estimates. Moreover, it is adaptable for scenarios in which signals may be received over multiple paths, including those affected by Doppler shift.
