Abstract: A shotgun magazine carrier for a competition shotgun to be attached to a competition belt or tactical belt. The carrier will fully attach to the magazine, so much so that it will remain on the magazine as it is installed onto the shotgun. The magazine will be configured such that it will remain in place as the competitor moves around the course whether in the mounted belt position or on the shotgun itself. The carrier consists of two parts, which can be made of metal or plastic, held together around the magazine with one or more fasteners. One of the two metal parts will be bent at a ninety-degree angle, in a clip shape, in order to fit directly over the competition or tactical belt securely next to the body of the user. The carrier will remain securely in place when in movement and during loading of the magazine.

Abstract: In order to determine whether a hybrid automatic repeat request (HARQ) indicator received by user equipment (UE) from a base station is an acknowledgment (ACK) or negative acknowledgement (NACK), when a signal representing the HARQ indicator is received by the UE, a plurality of symbols encoded in the received signal are determined to obtain a softbit for each of the symbols by summing an in-phase component and a quadrature component of each symbol. Thereafter, the softbits are summed up to be compared with the amplitude of the symbols to determine whether the HARQ indicator is an ACK or NACK.

Abstract: A system and method is provided for transmitting a signal to a plurality of slave devices (e.g., memory devices, etc.) via a communication circuit having a plurality of segments that are substantially equal in length and/or impedance. Specifically, according to one embodiment of the invention, an electronic system includes a processor, a plurality of memory devices, and a communication circuit (i.e., a bus) having a central node and a plurality of segments. Specifically, the plurality of segments are used to connect the plurality of devices (e.g., the processor, the plurality of memory devices) to the central node. For example, the processor is connected to the central node via a primary segment, the first memory device (M0) is connected to the central node via a first segment, etc. In one embodiment of the invention, the plurality of segments are substantially equal in length. In other words, the central node is substantially electrically-equidistant from each memory device. In another embodiment of the invention, the plurality of segments have substantially equal impedances. By arranging the plurality of memory devices in this manner (e.g., substantially electrically-equidistant from the central node, etc.), a well behaved signal can be received at each memory device.

Abstract: A MIMO system with Diversity processing is provided having Turbo Codes Decoders for computing orthogonal signals from multiple separate antennas. The invention decodes multipath signals that have arrived at the terminal via different routes after being reflected from buildings, trees or hills. The Turbo Codes Decoder with Diversity processing increases the signal to noise ratio (SNR) more than 6 dB which enables the Wireless system to deliver data rates from up to 200 Mbit/s. The invention provides several improved Turbo Codes Decoder methods and devices that provide a more suitable, practical and simpler method for implementation a Turbo Codes Decoder in ASIC (Application Specific Integrated Circuits) or DSP codes. A Turbo Codes Decoder block is provided to compute baseband signals from multiple different receiver paths. Several pipelined max-Log-MAP decoders are used for iterative decoding of received data. A Sliding Window of Block N data is used for pipeline operations. In a pipeline mode, a first decoder A decodes block N data from a first source, while a second decoder B decodes block N data from a second source during the same clock cycle. Pipelined max-Log-MAP decoders provide high speed data throughput and one output per clock cycle.

Abstract: A baseband processor is provided having Turbo Codes Decoders with Diversity processing for computing signals from separate antennas. The invention decodes multipath signals that have arrived at the terminal via different routes after being reflected from buildings, trees or hills. The Turbo Codes Decoder with Diversity processing increases the signal to noise ratio (SNR) more than 6 dB which enables the 3rd Generation Wireless system to deliver data rates from up to 2 Mbit/s. The invention provides several improved Turbo Codes Decoder methods and devices that provide a more suitable, practical and simpler method for implementation a Turbo Codes Decoder in ASIC or DSP codes. A plurality of parallel Turbo Codes Decoder blocks are provided to compute soft-decoded data RXDa, RXDb from two different receiver path. Several pipelined Log-MAP decoders are used for iterative decoding of received data. A Sliding Window of Block N data is used on the inputted data for pipeline operations. In a pipeline mode, a first decoder A decodes block N data from a first source, while a second decoder B decodes block N data from a second source during the same clock cycle. Pipelined Log-MAP decoders provide high speed data throughput and one output per clock cycle.
