Return characteristic information about channel filter
Determine Channel Filter Structure Dimensions
In a distributed MIMO system, send the same signal from two geographically separate transmitters (Tx) and combine the received signals at one single receiver (Rx) to explore spatial diversity. The two Txs are not co-located and they experience different multipath (path delays) to the Rx. Specify the path delays respectively.
delay1 = [0 1.5 2.3 5.2 6.6]; delay2 = [0 3.7 6.2];
Configure one channel filter object per Tx.
chanFilt1 = comm.ChannelFilter('PathDelays', delay1); chanFilt2 = comm.ChannelFilter('PathDelays', delay2);
info object function to get the ChannelFilterDelay and ChannelFilterCoefficients.
ans = struct with fields: ChannelFilterDelay: 6 ChannelFilterCoefficients: [5x21 double]
ans = struct with fields: ChannelFilterDelay: 4 ChannelFilterCoefficients: [3x19 double]
chanFilt — Channel filter
Channel filter, specified as a
infostruct — Characteristic information about channel filter
Characteristic information about channel filter, returned as a structure containing these fields:
ChannelFilterDelay — Channel filter delay
positive real scalar
Channel filter delay, returned as a positive real scalar.
ChannelFilterCoefficients — Channel filter coefficients
vector | matrix
Channel filter coefficients, returned as a vector or a matrix.
