segmentation tools for segmention lazy snaping

Since the first edition of this book was published seven years ago, the field of modeling and simulation of communication systems has grown and matured in many ways, and the use of simulation as a day-to-day tool is now even more common practice. With the current interest in digital mobile communications, a primary area of application of modeling and simulation is now in wireless systems of a different flavor from the `traditional ones. This second edition represents a substantial revision of the first, partly to accommodate the new applications that have arisen. New chapters include material on modeling and simulation of nonlinear systems, with a complementary section on related measurement techniques, channel modeling and three new case studies a consolidated set of problems is provided at the end of the book.

OFDM正交子载波调制，一种为BPSK，一种为QPSK，都经历串并转换后IFFT，加高斯白噪声信道而后反向解调。(modulate by BPSK&QPSK then use OFDM)
