Recently, there are a growing interest in the study of compressive sensing (CS). In this paper, we introduce CS to radar sensor network (RSN) within the pulse compression technique in order to efficiently compress, restore and then reconstruct the radar data. We employ a set of Stepped-Frequency waveforms as pulse compression codes for transmit sensors, and to use the same set of Stepped-Frequency...
The maximum transmission reach of 127 Gb/s DP-QPSK over legacy DMF link is extended to 4,800 km with 7.4 dB Q-factor using hybrid nonlinearity compensation and maximum likelihood sequence estimation, amounting to ∼37% distance increase.
We propose reverse concatenated code with inner BCH code and outer LDPC code. BCH decoder is based on MAP-decoding that provides high-accuracy-reliabilities for suboptimum-LDPC-decoder, leading to performance comparable to long-girth-12-LDPC codes, but with lower decoder-complexity.
A structure of non-adaptive decision-aided maximum likelihood is demonstrated by introducing a forgetting factor via both analysis and experiments, which achieves the same performance as the adaptive phase estimation while reducing the algorithm complexity.
Polarization-multiplexed LDPC-coded QAM robust to I-Q imbalance and polarization offset is proposed. Efficient mitigation of I-Q imbalance and polarization offset is demonstrated with LDPC-coded turbo equalization by simultaneous MAP detection of symbols transmitted over two orthogonal polarizations. The proposed scheme is much more efficient in I-Q imbalance and polarization offset compensation than...
We propose the reverse concatenated code as a forward error correction (FEC) scheme suitable for beyond 100-Gb/s optical transmission. In this scheme, BCH code is used as inner code and low-density parity-check (LDPC) code as outer code. The BCH decoder is implemented based on maximum a posteriori (MAP) decoding such as the BCJR/Ashikmin's algorithm, and an LDPC decoder is based on a min-sum-with-correction-term...
We experimentally demonstrate a novel decision-aided maximum likelihood phase estimation in an 8-Channel 42.8-Gbit/s DWDM coherent PolMux QPSK system. The results show that our proposed algorithm can achieve a comparable performance as the Mth-power while having much lower computational complexity.
Based on an extrinsic information transfer (EXIT) chart assisted receiver design, a low-complexity near-maximum a posteriori (MAP) detector is constructed for high-throughput MIMO systems. A high throughput is achieved by invoking high-order modulation schemes and/or multiple transmit antennas, while employing a novel sphere detector (SD) termed as a center-shifting SD scheme, which updates the SD's...
Iterative if-best sphere detection (SD) and channel decoding is appealing, since it is capable of achieving a near- maximum-a-posteriori (MAP) performance at a low complexity. However, a potentially excessive computational cost is imposed, especially in a high-throughput Spatial Division Multiplexing (SDM) aided OFDM system employing a large number of transmit antennas and/or high-order modulation...
