Title: Apparatus and method for correction of error
Inventor: NOGUCHI TATSUMI
IPC: G11B20/18
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To obtain an apparatus and a method whose efficiency is enhanced by a method wherein a parity in the other sequence is corrected on the basis of a correction operation by a parity in one sequence and, when its computing result is correct, all data in the other series are judged to be correct. SOLUTION: Reproduction data which is input to a data input terminal 1 is stored once in a RAM 10, and it is stored once in a RAM 30 via a deinterleave processing part 23. A parity computing part 40 executes a correction processing operation (a P1 processing operation) by a P-sequence parity and a correction processing operation (a Q processing operation) by a Q-sequence parity to the data in the RAM 30, and it executes a correction processing operation (a P2 processing operation) by the P-sequence parity again. When a parity in a next series is corrected on the basis of the correction processing operation in every series, a data operation and a flag operation are separated so as to be independent. Information which is generated in the data operation is reflected on a flag on the spot, and the parity is corrected only on the basis of a flag group in the flag operation.  Thereby, the degree of freedom of a processing operation is enhanced, and the processing efficiency of an error correction operation is enhanced.

Title: Logic circuit
Inventor: SHIMIZU HARUO
IPC: H03K19/0952
Filed: 1988-04-28
Abstract: PURPOSE:To suppress the fluctuation of the total current flowing to a differential circuit and to improve the stability of the circuit operation by connecting plural transistors(TRs) in series in a logic circuit provided with a constant current TR keeping a current flowing to a differential circuit constant. CONSTITUTION:The sum of currents flowing to TRs 1, 2 is kept constant by a constant current circuit 14, e.g., I3'. If an input bias voltage or a voltage of a power supply VEE of the TRs 1, 2 is fluctuated and a terminal voltage VX of the constant current circuit 14 is fluctuated by DELTAVX, the fluctuation width of VDS of the current TRs 12, 13 is DELTAVX/2. Since the voltage VX is shared equally by the constant current TRs 12, 13, the fluctuation width DELTAVX of the VX is shared equally by the constant current TRs 12, 13. Thus, the fluctuation width DELTAI3' of a current I3' is halved in comparison with a conventional value, that is, DELTAI3/2. Thus, the fluctuation width of a cross point Vcross is suppressed nearly to a half in comparison with a conventional value independently of the saturation characteristic of the TR 13 to improve the stability of the logic circuit 11.

Filed: 1988-04-28
Abstract: PURPOSE:To improve the data collection efficiency as the entire system by sending sequentially a retransmission permission signal at a time interval in response to the information representing the length of an excess data to each mobile station sending a retransmission request after the end of reception of a specified packet data from all mobile stations. CONSTITUTION:When a base station 10 sends a polling signal PS in an optional timing at first, each mobile station 20 sends packet data PD11-PD51 at each preset data transmission period based on a reception timing of the polling signal PS. The reference station 10 receives sequentially the packet data PD11-PD51 sent in time division from each mobile station 20 after the transmission of the polling signal PS and stores the data as a monitor data. A retransmission permission signal RS is sent sequentially after the end of reception of a packet data from all the mobile stations. Thus, the delay difference in the transmission timing between mobile stations is not expanded to reduce the transmission end time of the data sent from one mobile station thereby improving the data transmission efficiency of the entire system.
