Abstract: There is provided an apparatus and method for using QOF (Quasi-Orthogonal Function) Walsh codes when enough orthogonal Walsh codes are not available for a packet data service in a mobile communication system supporting concurrent provision of a high rate packet data service and a circuit call service. A data rate (DR1) in the case of using available orthogonal Walsh codes is first obtained. Then, a data rate (DR2) in the case of using QOF Walsh codes is obtained considering a power reduction factor due to the increase of interference involved with the use of the QOF Walsh codes. Packet data is transmitted at a higher data rate of DR1 and DR2. At the same time, information about the selected data rate and information about whether the QOF Walsh codes are used or not are transmitted.

Abstract: An apparatus for detecting a frame transmission period in a CDMA mobile communication system supporting a discontinuous transmission mode. A first frame detector performs primary frame detection by calculating a signal-to-interference ratio (SIR) using traffic symbol energy, pilot symbol energy and noise energy measured for a predetermined time period, and comparing the SIR with a predetermined frame detection threshold value. A decoder calculates a symbol error rate (SER) by decoding symbols received for the predetermined time period. A second frame detector selects an SER threshold value according to frame detection information from the first frame detector, and compares the selected SER threshold value with the SER to determine whether a frame has been transmitted.

An OFDM communication system using Q transmit antennas generates a base preamble sequence including a CP and an orthogonal sequence. If Q≦ a predetermined number M, a preamble sequence for a kth antenna is S(t−(k−1)T/M). If Q>M and k≦M the preamble sequence transmitted for the kth antenna is S(t−(k−1)T/M). If Q>M and k>M, the preamble sequence for the kth antenna is (−1)(PS−1)S(t−(k−M−1)T/M). Here, S(t) is the orthogonal sequence, T is the period of the orthogonal sequence, and PS is an index indicating a transmission period of the preamble sequence.

Abstract: An apparatus for detecting an on-off keying signal in a CDMA mobile station device is disclosed. A first calculator receives an on-off keying signal and a reference signal transmitted from a base station transmitter at a given transmission power level, despreads the received on-off keying signal, and generates a symbol power level of the despread on-off keying signal. A second calculator despreads the reference signal and generates a power level of the despread reference signal. A multiplier generates a variable threshold value by multiplying the power level of the despread reference signal by a gain determined by a ratio of the transmission power of the reference signal from the base station transmitter to the transmission power of the on-off keying signal from the base station transmitter. A comparator compares the variable threshold value with the symbol power level of the despread on-off keying signal. Further, a symbol detector detects the symbol of the on-off keying signal by comparing a comparison value from the comparator with a prescribed threshold value.
