Abstract: PURPOSE: A method for measuring a cell field of a wireless fixed part in a DECT(Digital Enhanced Cordless Telecommunications) system is provided to simply measure the cell field of the wireless fixed part in a multi-cell environment. Therefore, a cell capacity can be optimized by an appropriate structure of the private wireless fixed part. CONSTITUTION: A system forms a communication path between a wireless terminal having a wireless fixed device function, a terminal simulating a real wireless fixed device and a simulation wireless terminal capable of tranceiving, and enters an error rate checking mode. When the system enters a BER(Bit Error Rate) checking mode, the simulation wireless terminal transmits a constant data pattern, and stores transmitted data in a buffer. The wireless terminal having the wireless fixed part function receives the data, and transmits a constant data pattern. The simulation wireless terminal receives the data of the wireless terminal having the wireless fixed part function, and compares the data transmitted by the simulation wireless terminal with the data of the wireless terminal having the wireless fixed part function. The simulation wireless terminal calculates an error rate, and compares whether the error rate is larger than a setup error rate. If not, the simulation wireless terminal displays a compared result. If the error rate is larger than the setup error rate, the simulation wireless terminal transmits an alarm sound to display a result.

Abstract: PURPOSE: A compensatory control method for target injection timing is provided to stably operate a vehicle without shortage of injection time and torque fluctuation due to change of a mode. CONSTITUTION: A target injection timing compensation is controlled by the following steps. Fuzzy operation is performed by calculating basic target injection time, target air amount and target injection time(30-31). Target injection time is compared to a minimum reference injection time during fuzzy operation(32-33). The performance of lean operation is decided. If the target injection time is less than the minimum reference injection time or an engine is in a lean operation mode, the target injection time is corrected. The corrected target injection time is reduced according to the present air amount. Operation is continued while purge amount is maintained by the reduced air amount. By increasing or decreasing target injection time according to injection amount and air amount, an engine is operated stably.
