METHOD FOR GENERATING INTEGRATED PREAMBLE FOR SELECTIVE CODING SUPPORT, AND DIGITAL ORTHOGONAL TRANSMISSION SYSTEM AND METHOD USING IT

摘要

An integrated preamble generation method for a selective coding support, and a digital orthogonal transmission system and a method using the same are provided to reduce power consumption by implementing a preamble using a little code with a little number of memory. A digital orthogonal transmission system includes a transmission symbol generation unit(40), a control unit(400), a preamble generation unit(403), an encoding unit(404), and a transmission signal generation unit(41). The transmission symbol generation unit generates a transmission symbol data. The control unit generates a control signal which indicates a supporting of a predetermined coding scheme. The preamble generation unit generates a preamble which does not support the coding scheme or the preamble for supporting the coding scheme in a response to the control signal. The preamble generation unit couples the preamble to the transmission symbol data and generates sub-frames. The encoding unit codes the sub-frame for a coding support and bypasses the sub-frame for a coding non-support of the sub-frames outputted from the preamble generation unit in response to the control signal. The transmission signal generation unit generates an orthogonal transmission signal for an output data of the encoding unit.
