an error generator (21) for delivering, from said input sequence (xk), the data sequence (ak) and an error sequence (ek) to be used in both loops,
orthogonal control functionality means (40) for deriving a condition for the adaptive equalizer (EQ) to fulfill in order to decrease interference between said equalizer’s adaptation loop and said timing recovery loop.
2. A receiver as claimed in claim 1, wherein the control loop further comprises spatial conversion means (SI) for converting a given initially T-spaced sequence generated within the control loop into an equivalent Ts-spaced sequence for controlling said equalizer coefficient vector (Wn).
3. A receiver as claimed in claim 2, wherein said spatial conversion means (SI) are arranged to perform a linear interpolation.
4. A receiver as claimed in claim 2, wherein said spatial conversion means (SI) are arranged to perform a nearest-neighbor interpolation.

an orthogonal control step (40) for deriving a condition for the adaptive equalizer to fulfill in order to decrease interference between said control loop and the timing recovery loop.
7. A computer program product for a receiver computing a set of instructions which when loaded into the receiver, causes the receiver to carry out the method as claimed in claim 6.
8. A signal for carrying a computer program, the computer program being arranged to carry out the method as claimed in claim 6.
