please code c++ or java with screen shots of output

Q1: Given the 4-Ary Walsh code in the diagram below, to show how a Bit array B=(1-1-1 1] was communicated using CDMA. Must show all steps of encoding and decoding. The spreading code C must be unique for each user. Ideally, they are orthogonal to one another, i.e. 1 C, C3 = 0, unless i = k = J, 11 1-11 -1 1 - 1 - 1 -1 1 4-Ary Walsh Codes Example: Walsh Codes For a spreading factor J-4, there are 4 Walsh codes In general there are always J Walsh codes, as long as J = 2, 4, 8, 16, 32, 64, 128
