1.	Which of the following is a blind algorithm?(a) Linear adaptive algorithms(b) Constant modulus algorithm(c) Non-linear adaptive algorithms(d) Spatially adaptive algorithmsThe question was asked in examination.My question is taken from Fundamentals of Equalization in portion Equalization, Diversity and Channel Coding of Wireless/Mobile
Answer» RIGHT answer is (b) Constant MODULUS algorithm The explanation is: Blind algorithm technique uses algorithms such as the constant modulus algorithm (CMA) and the spectral coherence restoral algorithm (SCORE). CMA is used for constant ENVELOPE MODULATION and FORCES the equalizer weights to maintain a constant envelope on the received signal.
