Description: A MATLAB program has been written to investigate Orthogonal Frequency Division
Multiplexing (OFDM) communication systems. This program is valuable for future researchers
simulating systems that are too theoretically complex to analyze. Single-carrier QAM and multicarrier
OFDM are compared to demonstrate the strength of OFDM in multipath channels. Two
graphical user interface demonstrations show some of the basic concepts of OFDM. Platform: |

Description: 同时具有时间选择性和频率选择性衰落的无线通信信道，我们称之为双选择性衰落信道[1-4]。研究在双选择性衰落信道下，实现最优的收发机设计，使其尽可能减小时频双选衰落，尤其是时间选择性衰落对系统性能的影响，提高系统对多普勒扩展和时延扩展的鲁棒性，对实现高速移动下的高速率、高质量的宽带传输具有十分重要的意义。-We consider the estimation of doubly selective wireless channels within pulseshaping
multicarrier systems (which include OFDM systems as a special case). A pilotassisted
channel estimation technique using the methodology of compressed sensing (CS) is
proposed. Platform: |

Description: Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier modulation and multiplexing technique
proposed for 3G, 4G LTE-A systems to achieve higher data rates with better spectral efficiency at low latency. Time
varying nature of the wireless channel can cause frequency selectivity and multipath fading which affects performance of
the system badly. Platform: |

Description: High Peak to Average Power Ratio (PAPR) is a critical issue in multicarrier communication systems using Orthogonal Frequency Division Multiplexing (OFDM), as in the Second Generation Terrestrial Digital Video Broadcasting (DVB-T2) system. This
problem can result in large performance degradation due to the nonlinearity of the High Power Amplifier (HPA) or in its low
power efficiency. Platform: |
