Now-a-days, LTE (Long Term Evaluation) network becomes more popular and main issue regarding LTE network is indoor coverage. In LTE spectrum is limited so to increase spectral efficiency most of the operator deploy single frequency network but this also increase level of interference. Femtocell deployment inside macro-cell network can reduce indoor coverage issue but unplanned placing of femtocells as per user requirements may create interference between femtocells which is called as "Co-tier interference" which may have an impact on the overall performance of femtocells.
