摘要： A method for detecting and decoding a signal in a communication system based on Multiple-Input Multiple-Output (MIMO)-Orthogonal Frequency Division Multiplexing (OFDM). A signal is received through multiple receive antennas. A decision error occurring at a symbol decision time is considered and a symbol is detected from transmitted symbols. Original data transmitted from the detected symbol is recovered. The performance of a coded bit system can be significantly improved using a new equalization matrix G considering a decision error.

摘要： A method and apparatus for transmitting a preamble for frame synchronization and channel estimation in a MIMO-OFDM communication system are provided. 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. The preamble sequences are at least twice transmitted from the Q transmit antennas.

摘要： 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.

摘要： A receiving device for a mobile station receives signals transmitted from a base station having a time-switched transmission diversity (TSTD) function. In the receiving device, a despreader despreads channel signals which have been transmitted in a TSTD mode of operation. A pilot separator separates a pilot signal from the despread channel signals. A channel estimator generates a channel estimation signal by selecting pilot signals transmitted from a same antenna of a transmitter according to a TSTD pattern of the transmitter. A compensator compensates the channel signals with the channel estimation signal.
