Investigation of Non-Overlapping Time-Domain Windowing for OOB Radiation Reduction of OFDM System
(Institute of Electrical and Electronics Engineers (IEEE), 2019-03)
Orthogonal frequency-division multiplexing (OFDM) systems suffer from significant out-of-band (OOB) radiation. All existing techniques have several drawbacks as wasting spectral or time resources. Time domain windowing is ...
Ldpc Code Construction using Randomly Permutated Copies of Parity Check Matrix
A construction technique is proposed for low-density parity check (LDPC) codes. It uses a base parity check matrix designed from a ran-dom or constructed construction method as Gallager or Quasi-Cyclic LDPC (QC-LDPC) codes ...
