Abstract: A sound source separation method, applied in a sound system, is provided. The method comprises choosing a maximum sound source signal and at least a non-maximum sound source signal from a plurality of sound source signals; multiplying the at least a non-maximum sound source signal by at least a suppression value, to generate at least a suppressed sound source signal; and performing a back-end sound source extraction operation on the maximum sound source signal and the at least a suppressed sound source signal.

Abstract: A dynamic crossband link method is provided, which includes utilizing a local forwarding module to transmit and receive packet data to and from a client device via a first frequency band; obtaining a plurality of communication quality indicators corresponding to a plurality of uplink forwarding modules; and determining to transmit the packet data to a wireless access device and receive the packet data from the wireless access device via one of the plurality of uplink forwarding modules according to the plurality of communication quality indicators.

Abstract: An automatic access point (AP) deployment method executed within an indoor environment by an automatic AP deployment device includes: building a coordinate map of the indoor environment; setting a request information, while the wireless APs at least include one Wi-Fi AP and one Bluetooth AP respectively corresponding to Wi-Fi AP deployment plans and Bluetooth AP deployment plans; calculating a fitness value for each of the Wi-Fi and Bluetooth AP deployment plans; calculating an overall fitness value, and determining whether the overall fitness value is satisfied with a convergence condition; exchanging the deployment position values of at least two Wi-Fi AP deployment plans and at least two Bluetooth AP deployment plans; and changing at least one deployment position value of at least one Wi-Fi AP deployment plan and at least one Bluetooth AP deployment plan and again calculating the fitness value for each Wi-Fi and Bluetooth AP deployment plans.

Abstract: Disclosed are a wireless positioning method and a wireless positioning device. When the wireless positioning device is off-line, the information relevant to at least one Wi-Fi access point, at least one Bluetooth access point and at least one reference point is stored. When the wireless positioning device is on-line, the target position of the wireless positioning device is calculated according to the stored information.

Abstract: A dynamic crossband link method includes utilizing a local forwarding module to receive packet data from a client device via a first frequency band, obtaining a first communication quality indicator corresponding to a first uplink forwarding module and a second communication quality indicator corresponding to a second uplink forwarding module, and determining to transmit the packet data to a wireless access device via the first uplink forwarding module or via the second uplink forwarding module according to the first communication quality indicator and the second communication quality indicator.
