有多徑信道、多普勒頻移，瑞利、RICE(萊斯)信道等仿真，QPSK調制和解調等，交織編碼。程序經過本人測試，絕對可用，并附上本人測試說明和仿真圖像結果-I collected information on 2, how-path channel, Doppler frequency shift, Rayleigh, RICE (Rice) channel, such as simulation, QPSK modulation and demodulation, etc., Interleaved Coded. After I tested the procedure is absolutely available, along with my test images and simulation results indicate.
function [R,k,b] = msc(A)
% 多元散射校正
% 輸入待處理矩陣，通過多元散射校正，求得校正后的矩陣
%% 獲得矩陣行列數
[m,n] = size(A);
%% 求平均光譜
M = mean(A,2);
%% 利用最小二乘法求每一列的斜率k和截距b
for i = 1:n
a = polyfit(M,A(:,i),1);
if i == 1
k = a(1);
b = a(2);
else
k = [k,a(1)];
b = [b,a(2)];
end
end
%% 求得結果
for i = 1:n
Ai = (A(:,i)-b(i))/k(i);
if i == 1
R = Ai;
else
R = [R,Ai];

The idea of writing this book entitled “Cognitive Networked Sensing and Big Data”
started with the plan to write a briefing book on wireless distributed computing
and cognitive sensing. During our research on large-scale cognitive radio network
(and its experimental testbed), we realized that big data played a central role. As a
result, the book project reflects this paradigm shift. In the context, sensing roughly
is equivalent to “measurement.”
The term economics is generally understood to mean sound
management. This is associated with openness, good faith, accurate
figures and integrity in company accounts, with transparency ensured
through satisfactory standards of good practice in relation to investors
and the clients who have placed their trust in an organization’s
managers.
The telecommunications industry is undoubtedly in a period of radical change with
the advent of mobile broadband radio access and the rapid convergence of Internet
and mobile services. Some of these changes have been enabled by a fundamental
shift in the underlying technologies; mobile networks are now increasingly based
on a pure Internet Protocol (IP) network architecture. Since the first edition of this
book was published in 2009, a multitude of connected devices from eBook readers
to smartphones and even Machine-to-Machine (M2M) technologies have all started
to benefit from mobile broadband. The sea change over the last few years is only the
beginning of a wave of new services that will fundamentally change our economy, our
society, and even our environment. The evolution towards mobile broadband is one of
the core underlying parts of this revolution and is the focus of this book.
