“…An enhanced CRS interference cancellation receiver for LTE-A network is proposed [9]. The main idea of this scheme is to produce a soft evaluation of the useful signal using the turbo decoding and cancels this from the overall received signal prior to the approximation of the interfering CRS channels.…”

-In the recent years, heterogeneous network (HetNet) is used to improve the spectral efficiency and network capacity of Long Term Evolution-Advanced (LTE-A). Although, it has huge traffic congestion due to numerous numbers of mobile users and data terminals, leads to problems of cooperation between Macro-cell and Pico-cells. One of the major interference sources in LTE-A is Common Reference Signal (CRS) which is transmitted by neighboring cells across the entire frequency band. There are two categories of CRS interference, such as non-colliding CRS and colliding CRS interference. So, these type CRS interferences become the restricting factor for achieving higher throughput in downlink LTE-A. In this paper, an efficient equalizer for mitigating non-colliding CRS and Enhanced Space Alternating Generalized Expectation-Maximization (ESAGE) with a maximum aposteriori (MAP) criterion for colliding CRS interference cancellation is used. The simulation outcomes show that the proposed efficient equalizer and ESAGE-MAP provides better CRS interference cancellation than existing techniques.
