In Speex narrowband mode,the input data are exactly 160 samples with each sample consisting of 16 bits.It can create corresponsive compressed data by set quality.

於Speex narrowband中人人干,人人草，每160個且為16 bits的樣本中，設(shè)定相對應(yīng)的品質(zhì)可以得到相對應(yīng)的壓縮大小

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.

There are few equivalent circuit modeling methods for UWB antennas. This thesis compares the characteristic of some existing modeling methods and presents a general and precise modeling method for UWB antennas. Firstly, establish the narrowband model of the antenna, and compute the difference between input admittances of the antenna and its narrowband model. Secondly, implement rational approximation of the difference to build the macromodel, and convert it into SPICE equivalent circuits. Lastly, combine the narrowband model and the macromodel to form the ultimate equivalent circuit model of the antenna.
