摘要： To optimize the selection of pre-coding vectors in a multi-user MIMO system, the present invention provides a method for selecting pre-coding vectors in a base station, comprising the steps of: transmitting a plurality of pilot signals without being precoded to the plurality of terminals; receiving a plurality of feedback signals from the plurality of terminals, wherein at least one feedback signal includes a plurality of recommended pre-coding vector information and a plurality of channel status information, and each of the channel status information corresponds to a recommended pre-coding vector information; generate a pre-coding codebook based on the plurality feedback signals, wherein at least one pre-coding vector in the pre-coding codebook is determined based on a correlation coefficient between at least two recommended pre-coding vectors; and performing a transmission operation using the pre-coding codebook. Through considering the correlation among pre-coding vectors and different channel status information corresponding to different pre-coding vectors, be used to extend the selection range of pre-coding vectors and improve the total transmission rate of the whole system and system capacity.

摘要： The invention is a unique high speed Programmable Logic Device ("PLD") AND array with separate nonvolatile memory. The invention utilizes a separate nonvolatile memory to isolate the effect of nonvolatile transistors from the proper operation of the PLD AND array. The invention also results in a substantial increase in the amount of current flowing through transistors charging and discharging the PLD AND array bit lines. This in turn significantly increases the speed of the invention's PLD AND array. Moreover, the invention makes the current charging or discharging the PLD AND array bit lines more predictable. These advantages of the present invention are achieved by a nonvolatile memory that is separate from the AND array itself and also by utilizing NMOS transistors in the AND array instead of using the prior art nonvolatile transistors such as EEPROM transistors in the AND array.

摘要： An integrated circuit has an E-fuse sense circuit configured to produce a READ voltage according to a fuse resistance of an E-fuse during a READ operation. The integrated circuit also has a reference sense circuit configured to produce a reference voltage according to a reference resistance of an on-chip reference resistor during the READ operation. The reference sense circuit replicates the E-fuse sense circuit. The E-fuse sense circuit and the reference sense circuit are coupled to a comparator that produces a bit value according to a difference between the READ voltage and the reference voltage.
