According to the present invention, the strong interference signal can be reconstructed by utilizing the system matrix, and the interference cancellation can be performed for the received signal by utilizing the reconstructed strong interference signal. The complexity of the operation for the matrix inversion can be reduced and the performance of the apparatus can be improved by reducing the order of the matrix, and thus the efficiency of the process for cancelling the interference can be increased. | 2013-10-31 |
20130287088 | Receiver Having Limiter-Enhanced Data Eye Openings - A communication system having a receiver with a linear path and a nonlinear path. As the receiver receives a data signal, it adaptively equalizes the received signal, and amplitude-limits the equalized signal in the nonlinear path using a saturable amplifier limiter or the like. A slicer extracts data from the limited equalized received signal. In the linear path, a clock recovery circuit generates a clock signal from the equalized received signal. A delay circuit in the linear path at least partially compensates for propagation delay in the limiter. Having the clock recovery occur in other than the nonlinear path, a low jitter clock is generated. The limiter enhances the vertical opening of the data eye by increasing the rise and fall times of the limited signal, providing more noise margin for the slicer to operate with and a greater timing margin in which to sample the sliced data. | 2013-10-31 |
