Patent KR-20020021467-A (KR)
Inventor: KIM WANG RAE
IPC: H04L27/36
Filed: 2000-09-15
Abstract: PURPOSE: An adaptive predistortion transmitter is provided to regularly improve entire nonlinear characteristics regardless of time or external environment changes, by detecting errors caused by changed nonlinear characteristics of a main amplifier and by adaptively changing a coefficient of a high-order function and a look-up table based on the detected result. CONSTITUTION: A direct IF up-converter(202) performs a preprocessing for an inputted signal, and adaptively changes a coefficient of a high-order function or a look-up table under the control of an error detector(212). A D/A converter(203) and a low pass filter(204) convert digital signals of the up-converter(202) into analog signals, and perform low-pass-filtering procedures. An up-converter(205) mixes the filtered signals with oscillating signals of an oscillator(209). A main amplifier(206) amplifies output signals of the up-converter(205) to output the amplified signals to a directional coupler(207). A delayer(208) delays an inputted signal for a predetermined time, and outputs the delayed signal. A down-converter(210) mixes signals fed back from the main amplifier(206) with the oscillating signals. An A/D converter(211) converts output signals of the down-converter(210) into digital signals. The error detector(212) compares distortion signals fed back through the A/D converter(211) with original signals inputted through the delayer(208), and adaptively controls predistortion operations of the direct IF up-converter(202) according to the compared results.

Title: Method for judging performing role switch in lmp of bluetooth
Inventor: PARK JAE HAN
IPC: H04W84/18
Filed: 2000-09-19
Abstract: PURPOSE: A method for judging whether a role switch performed in a bluetooth LMP(Link Manager Protocol) is performed is provided to know whether the role switch is performed in a device for requesting a connection setting when setting a connection between buletooth devices. CONSTITUTION: An LMP(12) of a connection setting start terminal receives a connection setting command(LMP_connection_req) from an HCI(Host Controller Interface)(10). The LMP(12) transmits a connection setting request message(LMP_host_connection_req)(18) to an LMP(14) of a device for setting a connection. The LMP(14) of a connection setting request receipt terminal notifies the receipt of the connection setting request message(18) to an HCI(16) and waits whether a host accepts the connection setting request. If the connection setting request is received from a host, the LMP(14) judges whether a role switch is performed with reference to a role parameter included in a command for admitting the connection setting request. In case of performing the role switch, the LMP(14) transmits an LMP_slot_offset(40) message to the LMP(12) for informing that the role switch is performed. In case that the LMP_solt_offset(40) message is received, the LMP(12) performs a flow to be suitable for the role switch.
