摘要： A method for transmitting a signal according to the present invention comprises spreading a control channel data through a PN code and generating a diffused control channel data; time division multiplexing the diffused control channel data and a service channel data and generating a multiplexed signal; and inverse Fourier transforming the multiplexed signal and generating an inverse Fourier transformed signal.Accordingly, in multi-hop communication, frequency efficiency is improved by not using different RF frequencies between a control channel and service channel, and applying a control channel and service channel through the TDM (Time Division Multiplexing) method, and the channel efficiency is improved by WAVE channel switching.

摘要： Disclosed are a base station and a mobile terminal for location detection, and a location detecting method. The base station in which a plurality of antennas having RF modules are installed transmits a signal including location information of each of the antennas to the mobile terminal. The mobile terminal carries out location detection by selectively using location information received from a GPS receiver or location information received from a DSRC transceiver. The base station and mobile terminal for location detection can perform location detection with high accuracy using the existing DSRC service. Thus, the base station and mobile terminal can carry out location detection having an error of approximately 10 m in downtown areas or buildings.

摘要： A diversity transmitting/receiving apparatus and method is provided, which is implemented using space-time trellis codes (STTC) constructed from a Pseudo Noise (PN) sequence set in a Direct Sequence (DS) CDMA system. The transmitter comprises a PN sequence generator, a space-time encoder, first and second modulators, and first and second multiple transmit antennas. The space-time encoder selects two of the multiple PN sequences to construct STTC, and space-time encodes data from a data source according to the STTC to output an Wary data symbol. The two modulators modulate the space-time encoded data according to the STTC. The two multiple transmit antennas wirelessly transmit outputs of the two modulators, respectively. By applying a method using space-time coding in a DS CDMA system including multiple transmit antennas, it is possible to achieve both diversity and additional coding gain and also to reduce multiple user interference by increasing the PN sequence length.
