Walsh Codes are most commonly used in CDMA applications orthogonal codes. These codes correspond to lines of a special square matrix called the Hadamard matrix. For a set of Walsh codes of length N, it consists of n lines to form a square matrix of n × n Walsh code. The IS-95 system uses 64 Walsh function matrix 64.Kênh tổng hợp giữa máy phát (Tx) và máy thu (Rx) có M T đầu vào và M R đầu ra,và vì vậy, được gọi là kênh MIMO.
