Abstract: A Universal Serial Bus (USB) keyboard-video-mouse (KVM) switch for connection between at least one host and at least one USB device is disclosed. The USB KVM switch includes a first virtual USB hub, a first virtual USB device, a microprocessor and a first multi-address USB device control module. The first virtual USB hub is configured to communicate with a first host. The first virtual USB device is configured to communicate with the first host via the first virtual USB hub, and is provided with endpoint setting data identical with that of a first USB device. The microprocessor is configured to generate the first virtual USB hub, and enumerate the first USB device in response to electrical connection of the first USB device to the USB KVM switch.

Abstract: A MIMO detection method for a receiver in a MIMO system using N-QAM for modulation, the MIMO detection method including generating a plurality of symbol vector sets and a plurality of search radiuses, selecting a candidate symbol vector set corresponding to a highest level of a multilevel structure of N-QAM constellation, generating a search space corresponding to a lower level of the multilevel structure of N-QAM constellation according to the selected candidate symbol vector set, confirming which level the search space corresponds to, and generating a detection signal according to the search space when the level of the search space is the lowest level of the multilevel structure of the N-QAM constellation.
