Abstract: PURPOSE: A method for transmitting voice data using a Native ATM API is provided to efficiently transmit voice data using a Native ATM API offering the QoS(Quality of Service) assurance and bandwidth negotiation of an ATM and to solve a delay variation in a given range through buffering. CONSTITUTION: A transmitting unit stores coded voice data in a buffer. The transmitting unit appoints Frame_Size and allocates the width of an image. The transmitting unit determines Frame_PDU_Size, based on Data_Size_Sent=0. In this case, one PDU(Protocol Data Unit) is transmitted by the MTU(Maximum Transmission Unit) through several times. Transmitting the PDU by the MTU, the transmitting unit compares Data_Size_Sent, the size of total transmitted data, with Frame_PDU_Size, the size of the PDU. In case that a value of Data_Size_Sent is identical to a value of Frame_PDU_Size, the transmitting unit judges whether the voice data of the PDU have been transmitted successfully.

Abstract: PURPOSE: A terminal for a mobile communication system is provided so that transmission spurious property can be improved by removing 8.192MHz clock noise of a baseband, by adding IQ low band filters to a preceding terminal of an QPSK modulator. CONSTITUTION: A low band filter(101) removes 8.192MHz frequency from a baseband signal processor by filtering an IF baseband signal. A QPSK modulator(102) modulates the baseband signal from the low band filter(101). An LC band filter(103) passes a necessary frequency band by filtering the intermediate frequency from the QPSK modulator(102). An auto gain controller(104) controls a gain of the transmission signal. A frequency up converter(105) converts the transmission signal from the auto gain controller(104) to a radio frequency. A radio frequency band filter(106) filters the radio frequency from the frequency up converter(105) to a predetermined band. A pre-amplifier(107) amplifies the output signal from the radio frequency band filter(106). A drive amplifier(108) amplifies the output signal from the pre-amplifier(107) to a predetermined level. A final amplifier(109) amplifies the output signal from the drive amplifier(108) As the result, transmission spurious property is improved without requiring a saw filter. In addition, current consumption of the amplifiers can be remarkably reduced by removing the loss of the transmission signal.
