Filtered orthogonal frequency division multiplexing (F-OFDM), a technology
which is being considered as a promising platform for beyond 4G era is
expected to help deliver the new features at millimeter wave in the new 5th
generation of cellular communication. Some of its key features notably better
spectral utilization, enhanced throughput and immunity to interference can
be enabling for the new cellular standards. These features of filtered OFDM
comes with strict requirements of filter design, guard tone managements, and
efficient channel state information harness. This paper is intended to propose
an intuitive channel estimation scheme which will allow efficient acquisition
of channel state information (CSI) through exploiting the redundant steps of
the conventional pilot training-based algorithms and by also using an
adaptive weight to expedite the minimization of the error between the
estimated values and the actual values. Various simulations will follow to
demonstrate the superiority of the scheme over traditional pilot-based
algorithms and thus prove its utility in the current 5G cellular era.
