This paper develops an optimization model to determine dynamic frequencies and timetables of buses based on dynamic programming to maximize the profits of bus carriers as well as the passengers. The paper focus more attention on the concept of ‘reality’ while studying the bus scheduling, such as the real-time traffic flow speed, the dynamic model of the passengers getting on or off the bus and the...
Power line communication is a promising candidate of smart grid applications. Organizations such as IEEE and ITU-T have published standards to cover applications of power line communication in smart grid. However, recent research reveals that indoor power line channel is a time-varying channel which may cause severe intercarrier interference to the OFDM systems in those standards. It is known that...
We propose a low-complexity carrier frequency offset (CFO) estimation method and an independent component analysis (ICA) based semi-blind equalization structure for multiuser and coordinated multi-point (CoMP) OFDM systems. A group of orthogonal sequences is employed to enable separation and simultaneous estimation of multiple CFOs, dividing the multi-dimensional search into series of low-complexity...
