Interference coordination and Resource allocation has emerged as one of the most attractive techniques for combating interference in next generation cellular networks, such as the 3GPP UTRAN Long Term Evolution (LTE), which operates with universal frequency reuse in order to exploit the whole frequency bandwidth in each cell. Inter-cell interference caused(More)
In this paper, we evaluate the choice of suitable quantization characteristics for both the decoder messages and the received samples in Low Density Parity Check (LDPC) coded systems using M-QAM (Quadrature Amplitude Modulation) schemes. The analysis involves the demapper block that provides initial likelihood values for the decoder, by relating its(More)
The multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) system, an attractive technique due to its robustness for time selective fading channels. The major drawback of orthogonal frequency division multiplexing (OFDM) systems is the high peak to average power ratio (PAPR), which results in signal distortion when the(More)
