The receiver calculates a cross-ratio parameter according to a first ideal receiving value and a first ideal conjugate receiving mirror of a first receiving signal and a second ideal receiving value and a second ideal conjugate receiving mirror of a second receiving signal. The receiver calculates an I-Q imbalance compensation parameter according to the cross-ratio parameter, the first ideal receiving value, the first ideal conjugate receiving mirror, the second ideal receiving value, the second ideal conjugate receiving mirror, the first receiving signal and the second receiving signal. The receiver compensates a third receiving signal according to the I-Q imbalance compensation parameter.

Abstract: A pre-culling method for the hidden surface removal of image objects is disclosed. The steps of the pre-culling method includes: transforming an eye coordinate from an eye space to a model space of a polygon when performing a rendering operation; and comparing a normal vector of the eye coordinate in the model space with the normal vector of each face of the polygon to determine whether each face of the polygon with respect to the eye coordinate is a front face or a back face.

Abstract: A two-way relay, a wireless apparatus and a signal processing method thereof are provided. The two-way relay comprises a transceiver and a processor. The transceiver receives a relay receiving signal including a first terminal transmitting signal transmitted by a first wireless apparatus and a second terminal transmitting signal transmitted by a second wireless apparatus. The processor, which is electrically connected to the transceiver, uses a mapping function to transform the relay receiving signal into a relay signal and enables the transceiver to broadcast the relay signal.

Abstract: A cup rack includes an upright cup body for receiving multiple cups in a stack, and a base for supporting the storage cups in the upright cup body and defining an access port for finger access to pick up the cups individually.

Abstract: An object carrying device includes a first net body, a frame, a front baffle panel, and a rear baffle panel. The first net body has a bottom portion and two lateral portions. The bottom portion has a front side, a rear side, and two opposing lateral sides. The two lateral portions extend from the two opposing lateral sides of the bottom portion, respectively, and face each other. The frame is clipped to the first net body and disposed at the outer periphery of the first net body. The front baffle panel is fixed to the frame and disposed between the front side of the bottom portion and the two lateral portions of the first net body. The rear baffle panel is fixed to the frame and disposed between the rear side of the bottom portion and the two lateral portions of the first net body.

Abstract: The present invention relates to a resource allocation apparatus, subscriber station, resource allocation method, and non-transitory computer readable medium thereof. The resource allocation apparatus may know the unoccupied partition of the wireless network resource and allocate the unoccupied partition to the SS of the femtocell network. Thereby, the SS of the femtocell network will not occupy the same network resource of the macro BS or other femto SS, and interference of between femtocell and macrocell or other femtocell is reduced effectively.

Abstract: A mobile station (MS), a base station (BS), a transmission method and a computer storage medium thereof are provided. When the MS requests a bandwidth from the BS, it may generate a selected transmission sequence and a quick access message. The selected transmission sequence comprises pre-defined bit information (e.g., a flow identification, a size of the bandwidth or the like), and the quick access message comprises a station identification of the MS. The MS may transmit the transmission sequence and the quick access message to the BS in a frame so that the BS may allocate the bandwidth to the MS according to the size of the bandwidth, the station identification and the flow identification. Thereby, the amount of the control signals needed when the MS requests a bandwidth from the BS may be decreased.

Abstract: A high-power base station and a low-power base station for use in a heterogeneous network system and transmission methods thereof are provided. Interference caused by the high-power base station in control channels of the heterogeneous network system are avoided effectively based on one of the following strategies: (1) transmitting control information of the low-power base station by the high-power base station in the same control channel; (2) transmitting control information of the low-power base station by the low-power base station attached with a user end in a specific control channel which is pre-defined by the low-power base station; and (3) transmitting control information of the low-power base station by the low-power base station in a specific control channel which is determined based on an offset allocated by the heterogeneous network system.

Abstract: A motion parameter estimating method, an angle estimating method and a determination method are provided. The methods are adapted for an electronic device. In the angle estimating method, a first frequency modulation continuous wave signal is first transmitted, and at least one antenna receives a second frequency modulation continuous wave signal resulted by a target reflecting the first frequency modulation continuous wave signal. Multiple motion parameters associated with the target are then obtained according to the first frequency modulation continuous wave signal and the second frequency modulation continuous wave signal. Multiple measured values corresponding to the at least one antenna are obtained according to the motion parameters and configuration parameters of the at least one antenna, respectively. Afterwards, the measured values are substituted into a formula to obtain an estimated angle between a preset direction of the electronic device and the target.

Abstract: Provided is a drawer structure including a carrying device and a holding device. The carrying device has a support and two position-limiting rods. The two position-limiting rods are disposed on two opposing sides of the support. The holding device is disposed above the carrying device, slides relative to the carrying device, and has a frame and a first stopping rod. The frame is disposed on the support and between the two position-limiting rods. The two position-limiting rods are positioned above the bottom of the frame. Front and rear ends of the first stopping rod are fixed to the frame and disposed at the frame. The first stopping rod has a long straight section, concave section, and short straight section. Front and rear ends of the concave section are connected to the long straight section and the short straight section, respectively. The bottom of the concave section penetrates the support.
