Finite-State Chart Constraints for Reduced Complexity Context-Free Parsing Pipelines
Finite-State Chart Reduced Complexity Parsing Pipelines
2015/9/10
We present methods for reducing the worst-case and typical-case complexity of a context-free parsing pipeline via hard constraints derived from finite-state pre-processing. We perform O(n) predictions...
Network MIMO with Linear Zero-Forcing Beamforming: Large System Analysis, Impact of Channel Estimation and Reduced-Complexity Scheduling
Linear Zero-Forcing Beamforming Large System Analysis Impact of Channel Estimation Reduced-Complexity Scheduling
2011/2/21
We consider the downlink of a multi-cell system with multi-antenna base stations and single-antenna user terminals, arbitrary base station cooperation clusters, distance-dependent propagation pathloss...
Reduced Complexity Decoding for Bit-Interleaved Coded Multiple Beamforming with Constellation Precoding
Complexity Decoding Bit-Interleaved Coded Multiple Beamforming Constellation Precoding
2010/12/8
Multiple beamforming is realized by singular value decomposition of the channel matrix which is assumed to be perfectly known to the transmitter as well as the receiver. Bit-Interleaved Coded Multiple...
A Reduced-Complexity Mixer Linearization Scheme
Reduced-Complexity Mixer Linearization Scheme
2009/9/4
Measurement results of the signals emanating from both IF and LO ports of a double balanced mixer are presented, and, thus, it is shown that the linearization of the output in a down-converting mixer ...
Reduced Complexity Precoding Based Peak-to-Average Power Ratio Reduction Applied to Optical Direct-Detection OFDM
Complexity Precoding Power Ratio Optical Direct-Detection OFDM
2015/8/4
DCT based precoding is proposed for PAPR reduction to improve the performance of optical OFDM at limited precoding complexity. Effective PAPR reduction and the resultant OSNR performance are shown.
