The need for people to communicate with each other anytime, anywhere has greatly expanded the field of wireless communication. Due to users demand for more and better wireless services, there is a need for higher transmission bandwidth. However, in a wireless communication system, adding bandwidth is not as easy as in a wire-line system. As a result, spectral congestion becomes a serious problem. A spectrally efficient modulation scheme based transceiver, which maximizes the bandwidth efficiency, is a very promising solution. To achieve spectral efficiency, certain modulation constraints are imposed, which lead to a more complex receiver design. As wireless communication becomes more popular, there is also a big demand for a more compact transceiver.
