In this paper, we propose a limited feedback-based interference alignment (IA) scheme suitable for two tier macrocell-femtocell heterogeneous networks. Firstly, an analytical expression for the total system sum rate loss due to the employment of limited feedback channel versions is derived. Then, a comparative simulation study is done between two I...
