Toward code division multiple access (CDMA) communications and data protection, we propose and analyze pseudorandom noise (PN) sequences generated from a 2‐dimensional array structure of shift‐registers. For any positive integers m and n, we construct PN sequences of period 2 mn –1 using an m×n array of registers and show that we can generate all shifted PN sequences as required by IS‐95x with the proper linear combination of available sequences.
