Feedback Overhead in the FDD Downlink Massive MIMO System

Table 8

Encoding of “MIMOMOSI” by LZWM.

Steps			Code	Dictionary	Number of coded bits
1			255		8
2				is known
3			77	is not in the dictionary: we test if (if this is true, we keep 257; otherwise, we send ),; and MI is encoded by 513	9
4			73	is encoded to 258	9
5			77	is encoded to 259	9
6			79	is encoded to 260	9
7				is known	9
8			259	is encoded to 261	9
9			83	is encoded to 262	9
10			73	is known	9
The output is 77, 73, 77, 79, 259, 83, and 73
