The transmitted signals which were modulated is a group of orthogonal sine signals as subcarrier and non-regular zerosquare waves that the code elements period is t as baseband coded formats.
它所发送的信号是由一组正交的正弦信号作为副载波,用码元周期为T的不归零方波作为基带码型调制而成的。

So, let's say that I take a unit square -- -- so, something that goes from zero to one both in x and y directions.
我现在用一个单位正方形——,在x和y方向上都是从0到1变化。

So anyway, this is the origin, and then the last side, y equals zero, x So, somehow, in the change of variables, this square becomes this triangle.
