A novel constant false alarm rate(CFAR)detection algorithm is proposed in this paper．The Biparameter CFAR detection is applicable tO Gaussian noise in non—coherent integration for radar dim target detection algorithm．The paper analyzed the probability of false alarm in theory．Monte—Carlo simulations demonstrate that the Biparameter CFAR processor has achieved about 5 dB SNR gains in detection performances comparable to the conventional cell—averaging CFAR processor．

The demand of high data rate services has been increasing very rapidly and there is no slowdown in sight. We know that the data transmission includes both wired and wireless medium. Often, these services require very reliable data transmission over very harsh environment. Most of these transmission systems experience much degradation such as large attenuation, noise, multipath, interference, time variance, nonlinearities and must meet the finite constraints like power limitation and cost factor. One physical layer technique that has gained a lot of popularities due to its robustness in dealing with these impairments is multi-carrier modulation technique. In multi-carrier modulation, the most commonly used technique is Orthogonal Frequency Division Multiplexing (OFDM)
