iqscatterplot: IQ Scatter Plot

In algutier1/rwirelesscom: Basic Wireless Communications Simulation

Description

A convenience function that plots a scatter diagram of Im(r) vs. Re(r). The function is useful for visualizing constellations such as M-PSK or M-QAM.

Usage

iqscatterplot(r)

Arguments

Eb = Es/log2(M)
Nsymbols=10000
Nbits=log2(M)*Nsymbols
bits <- sample(0:1,Nbits, replace=TRUE)
s <- f8pskmod(bits)
EbNodB=7
No = Eb/(10^(EbNodB/10))
n <- fNo(Nsymbols,No,type="complex")
r <- s+n
