Abstract:
With the fast evolution in wireless communication standards and enhancement in cellular applications, the data rate requirement has increased exponentially over the past few
decades. The next generation wireless standards, therefore, need to provide ultra-high data
rates with minimum latency. Filterbank Multicarrier (FBMC) system is considered one
of most promising techniques so far in order to fulfill such high throughput requirements.
Along with that the advent of the era Software Defined Radio (SDR) has made the efficient
utilization of Radio Frequency spectrum or resource allocation a crucial parameter to be
considered. The need of communication depending upon the available channel conditions,
the data rate requirement and the Quality of Service(QoS) according to the application
at hand varies vastly. Having significantly reduced side lobes and complete elimination
of Cyclic Prefix (CP) as utilized in Orthogonal Frequency Division Multiplexing(OFDM),
FBMC provides with minimum Multiple Access Interference (MAI) as compared to the previously used waveform of SDR. Therefore, in order to requisite the high throughput demand,
the user requirements and channel quality, an adaptive algorithm should be devised aiding
the dynamic selection of optimum parameters providing diverse modes of operation for the
type of communication needed. The proposed link adaptation algorithm would incorporate
the required data rate, the available channel condition and the Quality of Service demand
and would dynamically allocate the optimally selected transmitting end parameters with
wideband FBMC waveform for the physical layer of SDR.
