Design of multicarrier pulses maximizing SINR by ISI/ICI shaping for the Doubly Dispersive channel

Multicarrier modulation (MCM) is a popularly used transmission technique. This paper aims at designing the multicarrier modulation pulse for communication over a Doubly Dispersive (DD) channel. For a DD channel, Inter Symbol Interference (ISI)\Inter Carrier Interference (ICI) can be completely eliminated only when we design the pulses with the knowledge of the channel state. But for a quickly varying doubly dispersive channel, the channel state cannot be tracked by the transmitter. So instead of designing a pulse which suppresses all the ISI\ICI, the proposed technique designs the MCM pulses which allows a tolerable ISI\ICI within the target pattern and eliminates all the ISI\ICI outside the target pattern. By properly selecting the target pattern, it is possible to treat the allowed ISI\ICI by using simple equalization/decoding techniques.
