Low-Density Lattice Codes for Inter-Symbol Interference Channels
Journal of Networks, 2013 Low-density lattice codes (LDLC) designed for inter-symbol interference (ISI) channels are proposed in this paper, including the node-by-node belief propagation (BP) decoding algorithm and the construction of LDLC codes for ISI channels. A theorem is presented to illustrate that the nominal coding gain of LDLC codes can be increased by introducing ISI ...

Realization of SRRC filter and multi-rate conversion based on FPGA
Dianzi Jishu Yingyong, 2018 In order to eliminate the inter symbol interference(ISI) in the communication system and improve the band utilization, the square root-raised cosine filter is often used to realize the base-band shaping filter of the baseband signal.

Research on the timing synchronization technology for PLC based on preamble sequence
Dianzi Jishu Yingyong, 2018 Because people do not consider the requirement of communication in the construction of power line, that resulting in the poor channel environment and the orthogonality between the sub-carriers are damaged.

Interference-Free OFDM: Rethinking OFDM for Interference Networks with Inter-Symbol Interference
, 2016 This paper considers a $K$-user single-input-single-output interference channel with inter-symbol interference (ISI), in which the channel coefficients are assumed to be linear time-invariant with finite-length impulse response. The primary finding of this paper is that, with no channel state information at a transmitter (CSIT), the sum-spectral ...
