What is offset QAM?

Offset quadrature amplitude modulation (offset-QAM) is a group of modulation formats in general communications [9], and has been investigated in multicarrier systems [10–12]. Recently, this concept was introduced to optical communications [13–17].

What is oqam?

A filter bank multicarrier (FBMC) with offset quadrature amplitude modulation (OQAM) (FBMC/OQAM) is considered to be one of the physical layer technologies in future communication systems, and it is also a wireless transmission technology that supports the applications of Internet of Things (IoT).
