Spectral efficiency analysis for LTE networks

This paper analyzes the uplink spectrum efficiency of an LTE network, taking intercell co-channel interference into account. This study is based on signal-to-interference-plus-noise ratio analysis and appropriate channel models including path loss and shadow fading. This paper also uses the proportional fair scheduling scheme to allocate resource blocks to improve the cell edge performance. The research results reveal that the intercell co-channel interference can cause up to 50% throughput reduction for cell edge users, but has almost no impact on cell centric user performance.
