std::ostream & | operator<< (std::ostream &os, UanPdp &pdp) |
Writes PDP to stream as list of arrivals. | |
std::istream & | operator>> (std::istream &is, UanPdp &pdp) |
Container class to describe power delay profile returned from UAN propagation models using tapped delay line model. This should model a channel impulse response as a set of equally spaced signal arrivals.
Generally, the profile should be normalized, such that the sum of all taps should equal 1. The received signal power on any interval (t1, t2) can then be found from summing the taps on the interval and multiplying by the total received power at the receiver.
