摘要
Device includes one or more recursive loops for estimation of a useful signal z(n). It comprises a first subtractive step where the received radio-electrical signal comprised of a radio-electrical signal x(n) and an interference signal yb(n) are processed to yield an intermediate useful signal y(n). The latter is then treated by a non-linear process to give an estimated useful signal z(n). A second subtraction step is executed starting from the original received signal x(n) and the first estimation z(n) of the useful signal to yield an interference signal s(n). Means for calculation of a signal error e(n) from y(n) and z(n) is included. A filter stage starts from the interference signal s(n) and using the error signal e(n) estimates the signal without interference. The process is repeated recursively or continuously.
