摘要： A transmission device for transmitting a signal in a wireless communication system is provided. The transmission device includes: a serial-to-parallel converter configured to convert an input serial bit stream into a parallel bit stream having three bits; and a phase rotation symbol mapper configured to map the parallel bit stream to a symbol having phase rotation characteristics, wherein when the parallel bit stream includes first to third bits, the phase rotation symbol mapper maps the second and third bits to a complex variable and sequentially maps a real number part and an imaginary number part of the complex variable to the front part and the rear part of a symbol in this order or to the rear part and the front part of the symbol in this order.

摘要： Provided are a receiving apparatus, a receiving method, a phase tracking apparatus, and a phase tracking method of a pulse-based UWB wireless system, which are capable of tracking and compensating phases of signals modulated with different modulation schemes in the same pulse-based UWB receiver system. The receiving apparatus of the UWB wireless system includes an orthogonal channel generating unit for receiving a baseband signal to generate orthogonal channels, a boundary detecting unit for receiving output signals of the orthogonal channel generating unit to detect boundaries of preamble, header and payload signals, a phase tracking unit for tracking and compensating phases of the preamble, header and payload signals output from the boundary detecting units, and a demodulating unit for demodulating output signals of the boundary detecting unit and the phase tracking unit to output data bits.
