Abstract: PURPOSE: A forward channel capacity increasing device of a wireless local loop is provided to increase an available channel capacity by sharing with a part of a power control signal for a time when data is not generated. CONSTITUTION: If an I channel and a Q channel are outputted normally, a control part(10) doesn't apply a control signal to a gain controller(160), and an I channel gain part(70) and a Q channel gain part(120) control a gain of an applied signal with an original set gain.

Abstract: PURPOSE: A device and a method for generating test patten data of an optical disk recording/reproducing system are provided to optimize a function of a data recording part. CONSTITUTION: An ECC encoder fetches a data applied from a host and converts the same into an ECC encoding data. A demodulator analyzes a header information of an optical data and outputs a record start signal. An EFM modulator receives the record start signal from the demodulator and converts a parallel data of 8 bit applied from the ECC encoder into an EFM serial data of 16 bit. A data recorder records the EFM serial data applied from the EFM modulator on an optical disk through a light pickup. A register stores each test pattern data. A serial data generator receives a register value according to a user's selection and generates a test pattern data stored in a pertinent register during a data field interval of a field time signal applied from the EFM modulator. A boundary smoothing data generator(304) checks a run-length of an EFM data sync signal and generates an adjusted boundary smoothing data at a boundary surface between a data field interval and a sync field interval of the field time signal, so that the run-length of the sync signal and the serial data, which are generated from the serial data generator(300), can be accorded with each other. A pattern mixing controller(302) inserts and mixing-outputs the boundary smoothing data into the boundary surface between the sync field interval and the data field interval of the field time signal so as to be continuous with the serial data. A multiplexer selectively outputs the EFM data and the test pattern data output from the pattern mixing controller(302) according to a switching control signal.
