ABSTRACT:
The proposed iterative method concurrently calculates maximum likelihood estimated values for the channel coefficients (h0, . . . , hL; θh) and the DC offset (d; θd) on the basis of a training sequence (TSC) in a TDMA mobile communications system. The SAGE algorithm leads to two recursion formulae, by means of which the iterative calculation of estimated values for the channel coefficients (h0, . . . , hL; θh) and for the DC offset (d; θd) is provided.
