spreadspectrum
In a normal communication channel, it is often desirable to concentrate the information in as narrow a region of the frequency spectrum as possible in order to conserve available bandwidth and to reduce power. The basic spread spectrum technique, on the other hand, is designed to encode a stream of information by spreading the encoded data across as much of
the frequency spectrum as possible. This allows the signal reception, even if there is interference on some frequencies. While there are many variations on spread spectrum communication, we concentrated on Direct Sequence Spread Spectrum encoding (DSSS). The DSSS method spreads the signal by multiplying it by a chip, a maximal length pseudorandom sequence modulated at a known rate. Since the host signals are in discrete-time format, we can use the sampling rate as the chip rate for coding.

可以看到
变步长未必会需要更长的时间
因为它是一种自适应的方式
如果某阶段情况理想的话
就会用最大步长来做
那就会很快
(can see variable step may not need a longer period of time because it is an adaptive way if a certain phase of the the ideal would be the greatest step will be to do it quickly)

bwlabel
说明: 为MATLAB中的图形增加标签,从而可以有效地表示图形意义,防止读不懂图的情况( BWLABEL supports 2-D inputs only, whereas BWLABELN support any
input dimension. In some cases you might prefer to use BWLABELN even
for 2-D problems because it can be faster. If you have a 2-D input
whose objects are relatively "thick" in the vertical direction,
BWLABEL will probably be faster otherwise BWLABELN will probably be
faster.)
