fbpskdemod: BPSK Demodulator

In algutier1/rwirelesscom: Basic Wireless Communications Simulation

Description

Receives a vector of real values, corresponding to a BPSK modulated signal transmitted through a communications channel (e.g., signal plus noise). An input value < 1 is mapped to an output value of 0, otherwise to a value of 1.

Usage

fbpskdemod(r)

Arguments

r	received signal vector

Value

returns a vector of 1's and 0's corresponding to BPSK demodulation of the input vector

Examples

Eb=1
Nbits=10
bits <- sample(0:1,Nbits, replace=TRUE)
s <- fbpskmod(bits)
EbNodB=8
No = Eb/(10^(EbNodB/10))
n <- fNo(Nbits,No)
r <- s+n
bitsr <- fbpskdemod(r)
biterrs<-bits[bitsr!=bits]
Pberr=length(biterrs)/length(bits)
