cmp_bits

Alignment of 2 bits vectors and counting the number of errors

Calling sequence

[b1,b2[,nerr,ber]] = cmp_bits(b1,b2);
[b1,b2[,nerr,ber]] = cmp_bits(b1,b2,'p',k); // Try to solve phase ambiguity (2^k-PSK)

Parameters

b1:

First bits vector (as output: realigned with b2)

b2:

Second bits vector (as output: realigned with b1)

nerr:

Number of errors (in bits) between the 2 realigned vectors

ber:

Bit Error Rate

Description

Try to find the best correlation between the 2 bit vectors and count the number of errors (ignoring the 2 first bits and 2 last bits).

Example

b1 = [0 1 0 0 0 1];
b2 =   [1 0 0 0 1];
[b1,b2,nerr,ber] = cmp_bits(b1,b2);
