用MATLAB在产生的观测数据中捕获其中PRN 号码为“5”C/A 码。
(1) 观测数据应该有一定的多普勒频偏D f(-10kHz〈D f〈+10kHz);
(2) 加入高斯白噪声,使其信噪比为-20dB;
(3) 捕获成功后,应给出捕获标志,并给出估计的频偏和码偏值。(Generated by MATLAB in which observed data capture PRN number is " 5" C/A code. (1) there should be some observations of Doppler shift D f (-10kHz < D f < +10 kHz) (2) by adding Gaussian white noise, so SNR is-20dB (3) capture success After the capture flag to be given, and given the estimated frequency offset and code bias values.)

(We designed and experimentally demonstrated a
Bragg grating-assisted wavelength-division-multiplexing filter for
the three-wavelength multiplexing on a planar-lightwave-circuit
platform. The 1310- and 1550-nm lights were designed to be
separated after passing the directional coupler by a half-cycle
and a full-cycle coupling actions with losses of 0.07 and 0.19 dB,
respectively. The 1492-nm light was reflected back by a Bragg
grating fabricated on the directional coupler and its loss was less
than 2.0 dB. We also introduced and discussed the new concept of
an integrated optical triplexer transceiver using this filter.)

ChebyshevExpansion
给定一个普通多项式p(x),用列向量表示,阶次从高到低排列,此函数返回p(x)的切比雪夫多项式展开的系数,返回的的结果也是一个列向量,同样按切比雪夫多项式的阶次从高到低排列
另外该函数用cos(x)项傅里叶级数展开一个多项式(
ChebyshevExpansion.m by David Terr, Raytheon, 5-26-04
Given a polynomial f(x) of degree n expressed as a row vector of coefficients of x^k with
highest power on the left, expand f(x) as a sum of scalar multiples of
Chebyshev polynomials, i.e. return the column vector of coefficients a_k with k
running from n to 0 from top to bottom such that f(x) = sum_{k=0}^n{a_k P_k(x)}.)
