摘要： A method of generating a BOC correlation function based on partial correlation functions, an apparatus for tracking a BOC signal, and a spread spectrum signal receiver system using the same are disclosed herein. The apparatus includes a frequency offset compensation unit, a local code generation unit, a mixer, a delay lock loop (DLL), a phase lock loop (PLL), and a data extraction unit. The frequency offset compensation unit outputs a compensated received signal with respect to a received signal. The local code generation unit generates a delay-compensated local code based on a code delay value. The mixer mixes the delay-compensated local code with the frequency offset-compensated received signal. The DLL repeatedly tracks and calculates a code delay value. The PLL repeatedly calculates a carrier frequency compensation value. The data extraction unit extracts spreading data from a mixture of the delay-compensated local code and the compensated received signal.

摘要： Disclosed herein are a spectrum sensing apparatus and method for a cognitive radio (CCR) network in a non-Gaussian noise environment and an FC apparatus and CCR system using the same. The cooperative cognitive radio (CCR) system includes M cognitive radios (CRs), and a fusion center (FC). Each of the M CRs samples a baseband signal obtained by down-converting a radio signal detected in the corresponding frequency spectrum, and generates spectrum sensing information (SSI) indicating that a PU signal has been detected based on the results of the sampling. The FC determines a joint threshold λFC that can maximize an expected average throughput of a secondary user (SU) signal in a given communication environment including a maximum interference condition, calculates a joint test statistic from received M pieces of SSI, and determines whether the PU signal is present by comparing the calculated joint test statistic with the joint threshold.
