Coaxial feed structures are widely used in ultra-wide band antennas . This paper modeled the characteristic of the monopole antenna feeded by coaxial line by FDTD in the time-domiain,which showes that . Firstly, it introduced the theory of the arithmetic and the particularly realization in the calcu ...

IN highly scattered enviroment，the Capacity of a MIMO channel with nt transmit antenna and nr recieve antenna is analyzed. The power in parallel channel (after decomposition) is distributed as water-filling algorithm

The following is a list of MATLAB codes which includes the radar absorbing material design, the antenna pattern, the observation points generation, and the amplitude error and phase error calculations.

contains pdf documents for MIMO in wirless communications, MI_NLMS adaptive beamforming algorithm for OFDM system, narrowband beamforming algorithm for smart antenna

contains documents related to adaptive beamforming algorithms for Wideband Code Division multiple access and a research article on circular patch antenna for C band altimeter system

implement basic routines in Matlab and Octave (currently using Matlab R13) for simulating adaptive beamforming and filtering for antenna arrays.

In 揚erformance of multi-carrier DS CDMA Systems?we apply a multi-carrier signaling technique to a direct-sequence CDMA system, where a data sequence multiplied by a spreading sequence modulates multiple carriers, rather than a single carrier. The receiver provides a correlator for each carrier, and ...
