Secondly, 4 methods of azimuth estimation based on vector hydrophone according to forms of nosie and signal are brought forward. The principles of these 4methods are set forth, simulating them by computer. Acoustic intensity averager can effectively suppress isotropic non-coherent interference; DOA based on line-spectra can effectively detect the target radiating line-spectra and estimate its azimuth angle; Bar graph approach can suppress line-spectra coherent interference and distinguish different targets radiating line-spectrum. Weighted bargraph approach can detect target in broadband coherent interference and estimate its azimuth angle.

The communication technology used in GPS is a direct sequence spread spectrum structure. Using C/A Gold codes, it can cope with wideband noise (such as thermal noise and channel noise) or low power narrowband interference by its processing gain. But DS-SS can not reject high power narrowband interference completely. So we need an anti-jamming filter to reject the narrowband interference by using adaptive filters prior to dispreading.

它是利用直接展频的一种架构，因此，此系统能藉由C/A码的展频处理增益，来对付ㄧ些宽频的干扰或是低能量的窄频干扰，但是它无法应付高能量的窄频干扰，因此我们需要一个抗干扰滤波器在解展频之前来先将干扰去除。

To extend the SIC technique to turbo-coded systems, an iterative IC with ordered SIC at front-end is proposed. To avoid unnecessary computation, the ordering information obtained from SIC front-end is utilized in a low-complexity stopping criterion with high efficiency. In addition to bit-wise interference cancellation, the SIC technique is also applied to code-block-wise interference cancellation. And, only the bits in incorrect blocks should be preceded to the next outer iteration. As a result, huge amount of computational complexity can be saved, and better performance is achieved.
