Abstract :
In this paper, we compare the Cramer-Rao bounds under the linear and norm constraints, for symbol and channel response estimation. It has been shown that, the norm-constrained CRB is smaller than the linear-constrained CRB, for multichannel FIR systems (SIMO) and synchronous CDMA systems (MISO).
