Title: Unipolar/bipolar conversion circuit
Inventor: KUWANA ISAMU
IPC: H03M5/18
Filed: 1991-11-07
Abstract: PURPOSE:To make the entire circuit small and to reduce the manufacture cost by devising the conversion circuit which converts an inputted unipolar signal into a bipolar signal and outputs the bipolar signal so that the circuit employs no transformer. CONSTITUTION:When unipolar signals U1,U2 at an H level are fed to TRs 3,4, the TR3 is turned on and the TR4 is turned off and an output terminal T3 reaches a positive potential. When the signal U1 reaches an L level, the TR3 is turned off and the TR4 is also turned off, then the output terminal 3 reaches a zero potential. When the signal U2 reaches an L level, the TR4 is turned on and the TR3 is turned off, then the output terminal 3 reaches a negative potential. Furthermore, when the signal U2 reaches an H level, since the TRs 4,3 are turned off, the output terminal reaches a negative potential. A bipolar signal B2 is outputted from the output terminal 3 by repeating the operation above. The signal is converted without using a transformer by forming the circuit as above, the entire circuit is made small and the manufacture cost is reduced.

IPC: H04L27/01
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To keep accuracy in data demodulation even in the case of frame synchronism with a delay wave. SOLUTION: The read signal of (T0-n) is sent from a response estimate timing generator 15 to a received signal memory 11, and the synchronizing signal of (T0-2n) is sent to a propagation path estimator 12. The propagation path estimator 12 sends a synchronizing symbol to a transversal filter 21, for which the number of taps is increased by (n) for preceding wave correction, and estimates a propagation path response while using the received signal. Concerning the estimated propagation path response, H(z) is calculated by adding the absolute value of (n) pieces of responses through a response selector 17. The response selector selects the maximum H(z) and sends it to a transmission sequence estimator 13. A deviation (z) from the leading frame position of the selected response is sent to a sequence estimate timing generator 16.  The frame position is adjusted forward and data can be demodulated while synchronizing the received signal read and the operation of the transmission sequence estimator.
