Unformatted text preview: accordingly. What is the spectral eciency of this set ST signals? (ii) (2 points) Can we get larger coding gain if we allow noninteger parameters u 1 and u 2 ? To answer this question, please determine parameters u 1 and u 2 by exhaustive searching in the interval [0 , L1] (you may use searching step 0 . 1 or smaller). What is the resulting normalized coding gain in this case? (iii) (4 points) Repeat questions (i) and (ii) for size L = 32. 1...
