Abstract: Receivers, methods, and cores, can provide decision feedback equalization with efficient burst error correction. An illustrative receiver includes: a decision feedback equalizer that derives symbol decisions from a receive signal; a subtractor that determines an equalization error for each said symbol decision; and a post-processor that operates on the symbol decisions and equalization error to detect and correct symbol decision errors. An illustrative receiving method includes: using a decision feedback equalizer to derive symbol decisions from a filtered receive signal; determining an equalization error for each said symbol decision; and processing the symbol decisions and equalization error to detect and correct symbol decision errors. An illustrative semiconductor intellectual property core generates circuitry for implementing a receiving and method as described above.

Abstract: A paper-type detection device comprises a sensor unit, a storage unit and a control unit. The sensor unit is used for detecting a transmission state of a paper according to a fixed clock period, and carrying out binaryzation on detected signals to indicate the presence-absence state of the paper. The storage unit is used for acquiring the signals detected by the sensor unit, acquiring paper information in the signals, and storing the paper information in sequence. The control unit comprises a first state counter and a second state counter. The control unit controls the two state counters for carrying out zero clearing and starting operations for counting in conjunction with the sensor unit.

Abstract: A paper money detection and counting device comprises: a sensor unit which is used for converting the output signals of a plurality of sensors distributed on a paper money transmission passage into a transmission state which characterizes whether paper money is present or not, each sensor corresponding to a paper money counter; a calculation unit which calculates the paper money distance between the current detection position of any sensor and the front end position of the currently detected paper money according to the transmission state output by the sensor unit; and a control unit, once the paper money distance calculated by the calculation unit goes beyond a paper money spacing standard value, the control unit looking up the transmission states output accumulatively by the sensors currently, when it is found that at least one transmission state characterizes that the paper money state changes from existence to nonexistence, adding 1 to the count value of the paper money counter corresponding to the sensor
