Abstract: An apparatus and a method for applying amplitude-differential phase shift keying are provided to maintain compatibility of main transmission data to a pre-differential phase shift keying and to improve a transmitting speed by modulating the main transmission data with a differential phase shift keying manner and modulating additional transmission data with the other differential phase shift keying manner. An apparatus and a method for applying amplitude-differential phase shift keying includes a first modulating unit modulating a first data sequence with a differential phase shift keying manner. A second modulating unit modulates a second data sequence with an amplitude shift and inserts a pilot signal to the amplitude shift modulated signal. A multiplier outputs after multiplying output data of first and second modulating units. The pilot signal is periodically or non-periodically inserted at a position of a sub-carrier of the amplitude shift modulated signal. A first demodulating unit(31) receives an amplitude-differential phase shift keying modulated signal and demodulates the received signal with the differential phase shift keying. A second demodulating unit(324) extracts the pilot signal from the received signal.

Abstract: PURPOSE: A method for assuming predetermined incidence angle/azimuth angle by using a steering vector is provided to record the predetermined incidence angle/azimuth angle in a recording medium by measuring the predetermined incidence angle/azimuth angle using a steering vector. CONSTITUTION: A steering vector is measured with respect to a first predetermined azimuth angle and a second predetermined incidence angle(200). Then, a dimension of an azimuth angle interpolation is determined(201). If a primary azimuth angle interpolation is selected, two azimuth angles are selected in order to determine an azimuth angle in a direction of the steering vector and a phase of a second incidence angle(202). If a quadratic azimuth angle interpolation is selected, one azimuth angle is selected in order to determine an azimuth angle in a direction of the steering vector and a phase of a second incidence angle. Then, a space spectrum is displayed by assuming the steering vector.

Abstract: PURPOSE: An incidence angle estimation method is provided to set a plurality of different sized virtual antennas, to apply an incidence angle estimation algorithm to each virtual angle, to average space spectra resulted from the application, to make the size of a pseudo signal less than that of a real signal, and to estimate an inclination angle on a real sensor by separating two more incident signals from one another. CONSTITUTION: The method comprises several steps. Arranged sensors sense signals(401). The sensed signals are converted into digital signals via a signal receiver, and transmitted to a processor(402). Then the processor extends virtually existing arranged sensors for setting a plurality of virtually extended arranged sensors(403). Each space spectrum of each arranged sensor is calculated by applying a space spectrum estimation algorithm to the virtually extended arranged sensors(404). Then one average space spectrum is calculated by using the plural calculated space spectra(405). A value of a pointed head in the average space spectrum is determined as an incidence angle(406), and is externally expressed on an angle display(407).

Abstract: PURPOSE: A synchronous protocol frame structure for a specific data service in a mobile telephone network using a CDMA(Code Division Multiple Access) system is provided to perform a voice call and to implement a protocol for reciprocal synchronizing in a traffic channel. CONSTITUTION: A primitive traffic is composed of two pieces of SI(Synchronizing Information) and one R/A(Request/Acknowledge). Each of the SI is composed of a 16-bit length preamble sequence, a 16-bit length message type, and 96-bit length information. The 16-bit length preamble sequence has a lowest frequency rate among sequences, which are not identical with a result for source-coding messages. The 16-bit length preamble sequence has a '0000x' type, and is capable of being changed. The 16-bit length message type is capable of deciding whether a message kind is an SI or an A(Acknowledge) or an NA(Non Acknowledge), and has a lowest frequency rate.
