Latest Patents

Ke Liu holds a patent titled "Layered Space Time Processing in a Multiple Antenna System." This patent describes a system and method for performing extended space-time processing. The invention focuses on generating an improved symbol decision for a desired sub-channel of the signal vector. It involves creating a baseline decision for the sub-channel and subtracting the contribution of the strongest sub-channel from the signal vector to produce a modified signal vector. The modified signal vector is then multiplied by a unitary matrix derived from a QR decomposition of another channel matrix. This innovative approach effectively cancels channel interference from the remaining sub-channels, enhancing the overall performance of the system.
