“…In addition, the discrete correlation function

R_{C_{n 1} C_{n 2}}

at the m th chip position for two binary sequences

C_{n 1} = C (n_{1}, p)

and

C_{n 2} = C (n_{2}, p)

is defined as :

R_{C_{n 1} C_{n 2}} (m) = \sum_{l = 0}^{L - 1} c_{n 1, l} . c_{n 2, (l + m)}

where

C_{n 1} & C_{n 2} \in {0,1}

, L is the code length and

| m | \leq L - 1

. Figures (a)–(d) show the correlation functions of all possible pairs of the code sequences for p = 5 synchronized UCMPC and T‐UCMPC.…”

“…The novel T‐UCMPC is constructed based on the UCMPC, which is explained in . Table shows code and binary sequences of UCMPC over Galois Field of 3 (i.e., p = 3 ) which is obtained by using the algorithms and formulas provided in . In this table, p is a prime number, i is the group number, x is the code index within a group, j is the subsequence index, n is the code index, and k is the bit index within the binary code sequence.…”

“…Various optical orthogonal codes have been proposed and evaluated in different optical CDMA networks in past few years , but proposing a novel code family which enhances the network capacity and its spectral efficiency is still an on‐going challenge. Many code families have been introduced recently which either are new prime code sets or modified version of existing prime code families (e.g., padded MPC (PMPC) , the new MPC (n‐MPC) , double‐padded MPC (DPMPC) and Transposed Modified Prime Codes (T‐MPC) ).…”

Recently, we have proposed a novel prime code family (i.e., Uniform Cross Correlation Modified Prime Code (UCMPC) ) which outperforms other available prime code families. UCMPC offers better spectral efficiency, lower bit error rate (BER), uniform and unity cross‐correlation, and higher security.…”
