Abstract
In this paper, we consider a MIMO system with two transmit ports and receiver ports in the power-line communications (PLC), and we propose two space time block codes (STBCs) Finite Feedback Schemes (FFSs) for PLC. In each scheme, the transmitter equips with two STBCs, one corresponding to each of the feedback values, to encode the information bits. Because of the impulsive noise in PLC channels, the feedback function and ML decoding metric for AWGN can't be applied, so we modify them to fit the generalized Gaussian distribution (GGD) impulsive noise with parameter beta in PLC. From the simulation, these two FFS schemes outperform the previous no feedback scheme for high bit rate (16bpcu) by 9.3dB and 10 dB, respectively, when beta=0.8 and BER=10-3. Previous FFSs in AWGN channels beta=2 are special cases of our schemes.
