Today, the authors have required to accommodate a large number of users under a single base station. This can be possible only if they have some flexibility over the spectrum. Previously they have lots of multiplexing methods to accommodate large number of signals in time and frequency domain. But now they have required to accommodate a large number of users in the same bandwidth, without any fading over the received signal. So, orthogonality can be maintained over the frequency response. This technology is now more popular in the mobile communication domain, called Orthogonal Frequency Division Multiplexing (OFDM).
