Title: John H Brady: Innovator in Differential MIMO Technology
Introduction
John H Brady is a notable inventor based in Madison, WI (US). He has made significant contributions to the field of telecommunications, particularly in the area of MIMO (Multiple Input Multiple Output) technology. With a total of 3 patents to his name, Brady's work has advanced the capabilities of data transmission and reception.
Latest Patents
One of his latest patents is the Differential MIMO transceiver, which involves a sophisticated method for detecting a plurality of information symbols. In this invention, a first signal and a second signal are received from two transmitted signals, which are sent by a first plurality of antennas and received by a second plurality of antennas connected to the receiver. The second signal is received after the first signal, and the receiver spatially filters the first signal using a spatial filter matrix. The receiver computes a conjugate of the first filtered signal to define a conjugate first signal, and spatially filters the second signal using the same spatial filter matrix. The receiver then computes a Hadamard product of the first filtered signal and the conjugate first signal to define a differential measurement signal, from which it detects the plurality of information symbols.
Another aspect of his patent involves a method of estimating a spatial filter matrix. In this process, a conjugate of a received first signal defines a conjugate first signal. A Kronecker product of the defined first signal and a received second signal defines a differential measurement signal. The computations are repeated for a plurality of first and second signals, which is sufficient to compute an estimate of a channel matrix from the differential measurement signals. A spatial filter matrix is then computed from this estimate and is used in a data communication phase between the first and second plurality of antennas.
