Microwave Data

Origin

This directory contains FIR models of digital microwave radio channel impulse responses. The complex-valued baseband channel responses have been "fractionally sampled" at twice the baud interval. The baud intervals vary somewhat from channel to channel, and are listed below.

chan1.mat (chan1a) : T = 30Mb
chan2.mat (chan2a) : T = 22.5Mb
chan3.mat (chan3a) : T = 30Mb
chan4.mat (chan4a) : T = 30Mb
chan5.mat (chan5a) : T = 22.5Mb
chan6.mat (chan6a) : T = 30Mb
chan7.mat (chan7a) : T = 30Mb
chan8.mat (chan8a) : T = 30Mb
chan9.mat (chan9a) : T = 30Mb
chan10.mat (chan10a) : T = 30Mb
chan11.mat (chan11a) : T = 30Mb
chan12.mat (chan12a) : T = 22.5Mb
chan13.mat (chan13a) : T = 22.5Mb
chan14.mat (chan14a) : T = 30Mb
chan15.mat (chan15a) : T = 30Mb

These responses were extracted from the processing of field measurements of received signals, courtesy of Applied Signal Technology, Sunnyvale, CA. The data is in the format of Matlab binary ".mat" files, readable from within Matlab via the "load" command. When loaded, the channel impulse response vector will have the variable name 'C'. Alternatively, you can download the "a" file (chan1a, for example) which has the same data as its ".mat" counterpart but in ASCII.
