The Communications Blockset 4 extends Simulink with a library of blocks for designing, simulating, and verifying the physical layer of communications systems. This version provides blocks for designing and simulating the physical layer of communications systems, including source coding, block-and-convolution coding, interleavers, filters, and modulators. The tool provides sources, including random-integer and binary generators and PN- and Gold-code sequences, as well as sinks, such as error-rate calculations, eye diagrams, and constellation plots. Features include integration with Matlab and Communications Toolbox for postsimulation analysis, and a channel-visualization tool for visualizing and exploring time-varying communications channels. Additional features include channel models such as AWGN, multipath Rayleigh and Rician fading, RF impairments; including nonlinearity, phase noise, thermal noise, and phase and frequency offsets. Available for Windows, Linux, Solaris, and Macintosh platforms, the Communications Blockset 4 costs $1000.
