Abstract: A method for monitoring an ideal diode comprises controlling a source-gate voltage of a MOSFET of the ideal diode such that the ideal diode can be changed between an off and an on state with a first target value for a source-drain voltage. To detect error states, the source-drain voltage and the source-gate voltage are measured. A check is carried out to determine whether the source-drain voltage reaches the first target value within predefined error limits in the on state. A test mode is carried out, in which a second target value, smaller than the first target value, is set for the source-drain voltage. A check is carried out to determine whether the source-gate voltage reaches an upper threshold value when the test mode is being carried out. An error signal is output when the first target value and/or the upper threshold value is/are not reached.

Abstract: A near-optimal Karhunen-Loeve basis expansion modeling (KL-BEM) orthogonal time frequency space (OTFS) receiver with superimposed pilots has been proposed for high-mobility communications with Doppler spread channel. First, an initial KL-BEM channel estimation is conducted by superimposed pilots, followed by the removal of superimposed pilots from the received OTFS signal and equalisation by message passing (MP) algorithm. After that, the detected data symbols are utilized as pseudo pilots along with the superimposed pilots to refine both KL-BEM channel estimation and equalisation in an iterative manner. Simulation results confirm the superior performance of the proposed KL-BEM OTFS receiver over the prior art in terms of the mean-square-error (MSE) of channel estimation and bit error rate (BER). It also has a close BER performance to the BER lower bound obtained by assuming perfect channel estimation. It contributes to high spectral efficiency and fast convergence performance.
