Feedback Overhead in the FDD Downlink Massive MIMO System

Algorithm 5

LZW feedback overhead encoding.

1: Initialize the dictionary with all integer values from to

2: Consider for each input binary sequence of length his BDC as a code

3:

4: =first input binary sequence of length

5: while not end of the input sequences do

6: =next input binary sequence of length

7: if the code of concatenated with is in the dictionary then

8:  Replace by concatenated with

9: else

10:   

11:   Output code of

12:   Add as the code of concatenated with in the dictionary.

13:   Replace by

14: Output the code of
