In the fifth generation mobile communications system (5G), it is expected to use millimeter wave (mmW) radio access with very wide frequency bandwidths of more than 1 GHz. To achieve good coverage and availability, high gain antennas or arrays are essential in order to compensate for the higher propagation loss experienced at mmW frequencies relative to current cellular bands. This paper presents...
This paper presents a 10 Gbps millimeter wave OFDM experimental system using a highly efficient modulation and coding scheme where iterative phase noise compensation can drastically alleviate performance degradation due to phase noise. 60 GHz frequency synthesizer in a silicon RF-CMOS IC suffers from relatively large phase noise, which severely degrades the performance of the 10 Gbps OFDM using 64QAM...
This paper presents decision-directed phase noise compensation (DD-PNC) by digital signal processing for millimeter-wave 60 GHz OFDM systems, and verifies the effectiveness of DD-PNC by using a 60 GHz OFDM experimental system. 60 GHz frequency synthesizer implemented in single-chip RF-CMOS IC suffers from relatively large phase noise, which severely degrades performances of the OFDM transmission with...
