SPECTRAL EFFICIENCY ANALYSIS OF MUTI CELL OFDMA SYSTEM WITH SECTORING

Blog Article

This paper analyses the performance of the multi cell OFDMA system for the average spectral efficiency and the coverage probability.We form the Chunk PURE BORAX by the grouping of the adjacent subcarriers by exploiting the correlation among them.Frequency band allocation is based on the chunk instead of the subcarrier in order to reduce complexity in the sub copyright based resource allocation.

In order to mitigate inter cell interference; in addition with Fractional Frequency Reuse (FFR), the proposed scheme introduces 3 additional directional antennas to provide 120 degree sectoring.This method provides better spectral efficiency than FFR without including sectoring.We achieve the optimal radius ratio ESTER-C 1000MG of 0.

6 for this proposed resource allocation scheme.Through simulation, we validate the analysis.
