  • Patent number: 10771132
    Abstract: Disclosed is a MIMO system including a transmitter and a receiver, in which an overall BER characteristic is improved. The transmitter (1) maps data, distributed among transmit antennas, onto an IQ plane to generate carrier symbols, and then, applies an inter-polarization interleave processing in a time direction to the carrier symbols between the transmit antennas, to generate OFDM signals. Receiving the OFDM signals, the receiver (2) demodulates the OFDM signals to generate complex baseband signals, and after that, applies a first deinterleave processing in a time direction to the complex baseband signals to generate time deinterleaved data. Further, the receiver (2) applies a MIMO separation processing to the time deinterleaved data to generate a plurality of sets of MIMO separated data and applies a second deinterleave processing between the receive antennas to the plurality of sets of MIMO separated data, so as to generate carrier symbols.

  • Patent number: 8463426
    Abstract: A computerized bulk parts control system and method. Parts are repacked (consolidated or divided) and palletized to prevent production problems such as unnecessary shortages of parts. Parts are traced from departure at a supplier's facility to arrival at a manufacturer's facility and then to production line side delivery. Traceability data is collected at various stages in the parts transportation, repacking, and delivery processes. The traceability data allows the manufacturer to evaluate information regarding the impact of late shipments and short shipments as well as changes in the production schedule. The computerized system and method creates a “part history” for each part that facilitates its delivery to the right place at the right time. The history allows the manufacturer to trace parts to their origins which is important for many quality control activities. The history also allows the manufacturer to track and replace parts used outside of a normal production sequence.
