This paper discusses the theory behind ultrawideband (UWB) transmit waveform design, and reports a proof-of-concept UWB radio testbed with waveform level precoding. Unlike a narrow-band channel, a UWB channel contains a large number of resolved multipath components, which opens a door for exploring new features offered by UWB. Waveform level optimization is meaningful, but it is a great challenge...
The novelty of multiple-input multiple-output (MIMO) radar is to improve the performance of radar utilising spatial diversity and waveform diversity. Proposed is the optimisation design of complete complementary sequence (CC-S) for MIMO radar based on channel capacity with the clutter statistical properties known. The method obtains the optimised CC-S through maximising the channel capacity of MIMO...
A new approach is proposed for measuring the group consensus in the multiple attribute decision making (MADM) problems with preference information on alternatives. In the approach, multiple decision makers give their preference information on alternatives in different formats. The uniformity and aggregation processes with fuzzy majority method are employed to obtain the social fuzzy preference relation...
This paper focuses on option pricing using a stochastic optimization algorithm. The underlying stock price changes according to a set of geometric Brownian motions coupled by a continuous- time finite state Markov chain. A recursive stochastic optimization algorithm is constructed to estimate the implied volatility. Convergence analysis of the algorithm is provided together with rate of convergence...
