In orthogonal signalling as k increase there is(a) Improved error perf

1.	In orthogonal signalling as k increase there is(a) Improved error performance(b) Degraded error performance(c) Improved bandwidth(d) None of the mentionedThis question was addressed to me in an online quiz.This interesting question is from Waveform Coding in portion Channel Coding of Digital Communications
Answer» The correct choice is (a) IMPROVED ERROR performance To EXPLAIN I would SAY: In orthogonal signalling as k increases there is improved error performance or a reduction in required Eb/N0 at the expense of bandwidth.
