question 2 ~ 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 1 1 1 - 1 -1 = 0, unless i = k = J, if i=k C C C C 1 - 1 - 1 -1 -11 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.... Q2: Give the 4-Ary Walsh code above; show how you construct a 8-Ary Walsh Codes
