Claim 7:
8. A method, performed by a second Antenna Processing Unit (APU) for sequential receive combining in a radio stripe system, wherein the radio stripe system comprises at least two APUs and a Central Processing Unit (CPU) the at least two APUs being connected in series from the CPU, wherein the radio stripe system serves at least two User Equipment (UEs), the method comprising:
obtaining channel estimates for channels to said served UEs;
receiving, from at least one preceding first APU, effective channels from said served UEs to said preceding first APU, the effective channels representing effective channels created after the at least one preceding first APU applies a first receive combining filter to each channel for said served UEs; and
determining a second receive combining filter based on the obtained channel estimates and the received effective channels from said at least one preceding first APU, wherein the second receive combining filter is going to be applied to received data signals.
