Question
True of false:
(a) ( T / F ) In BICM, one can either use a random interleaver, an S-random interleaver, a symbol interleaver or a bit interleaver between the code and the modulation.
(b) ( T / F ) In TCM, the high-order modulation is generally labeled by Gray labeling, which is also known as the Ungerboeck labeling.
(c) ( T / F ) It is enough to tell from the value of the syndrome whether a received sequence is a valid codeword.
(d) ( T / F ) BICM is most useful in a fading environment.
(n1, k1, di)Explanation / Answer
a) True as BICM can work with random interleaver, symbol interleaver or bit interleaver.
b) False. Ungerboeck labelling uses set partitioning.
c) True
d) True
e) True
