(2N)th number = x2 bit of the Nth symbol
Where,
x1: Either i1 or q1
x2: Either i2 or q2
If a channel’s modulation scheme is 4PAM for I branch and BPSK for Q branch, queried data represents
alternating i1,i2 and q(quad-phase bit) sequences as follows:
1st number = i1 bit of the 1st symbol for 4PAM on I branch
2nd number = i2 bit of the 1st symbol for 4PAM on I branch
3rd number = q bit of the 1st symbol for BPSK on Q branch
4th number = i1 bit of the 2nd symbol for 4PAM on I branch
5th number = i2 bit of the 2nd symbol for 4PAM on I branch
6th number = q bit of the 2nd symbol for BPSK on Q branch
…
(3N – 2)th number = i1 bit of the Nth symbol for 4PAM on I branch
(3N – 1)th number = i2 bit of the Nth symbol for 4PAM on I branch
(3N)th number = q bit of the Nth symbol for BPSK on Q branch
If a channel’s modulation scheme is BPSK for I branch and 4PAM for Q branch, queried data represents
alternating i(in-phase bit) and q1,q2 sequences as follows:
1st number = i bit of the 1st symbol for BPSK on I branch
2nd number = q1 bit of the 1st symbol for 4PAM on Q branch
3rd number = q2 bit of the 1st symbol for 4PAM on Q branch
4th number = i bit of the 2nd symbol for BPSK on I branch
5th number = q1 bit of the 2nd symbol for 4PAM on Q branch
6th number = q2 bit of the 2nd symbol for 4PAM on Q branch
…
(3N – 2)th number = i bit of the Nth symbol for BPSK on I branch
(3N – 1)th number = q1 bit of the Nth symbol for 4PAM on Q branch
(3N)th number = q2 bit of the Nth symbol for 4PAM on Q branch
If a channel’s modulation scheme is 4PAM for both I and Q branches, queried data represents alternating i1,
i2 and q1, q2 sequences as follows:
1st number = i1 bit of the 1st symbol for 4PAM on I branch
2nd number = i2 bit of the 1st symbol for 4PAM on I branch
3rd number = q1 bit of the 1st symbol for 4PAM on Q branch
4th number = q2 bit of the 1st symbol for 4PAM on Q branch
5th number = i1 bit of the 2nd symbol for 4PAM on I branch
6th number = i2 bit of the 2nd symbol for 4PAM on I branch
7th number = q1 bit of the 2nd symbol for 4PAM on Q branch
8th number = q2 bit of the 2nd symbol for 4PAM on Q branch
