Abstract:
The Long Term Evolution (LTE) for the third generation partnership project (3GPP) has recently
been focusing towards aggressive frequency reuse; so that maximum number of hands can be gotten
within a cell. Traditional frequency reuse concept for interference management doesn’t provide
satisfactory coverage and rate, thus fractional frequency reuse is chosen. In today’s wireless
communication system they are challenges regarding SINR and data rate like distance, probability of
coverage and probability acceptance rate. Fractioning the number of reuse to study the problem and
find better solution. The aim of this thesis is evaluate the performance of the interference
management of downlink OFDMA using FFR on MATLAB by comparing FFR with traditional
reuse concerning their performance and capabilities of both as schemas to find best solution. FFR is
purposed as a candidate for interference management and its comparative evaluation over traditional
frequency reuse on the basis of three parameters metrics probability of coverage, probability of
acceptance rate and frequency reuse factor are done and FFR has relatively better performance.
Further improvements in both data rate and SINR can be achieved FFR implementation. The
simulation results show that FFR has better performance in SINR the traditional reuse better, similar
to reuse 3and coverage around 200% more then it in particular SINR. Moreover the data rate value
of FFR is more then 200% and nearly 300% regarding to reuse 1 and respectively.
