ABSTRACT:
A first bit estimate value for a first data stream is determined from a signal y0received by a first antenna, and a second bit estimate value for the first data stream is determined from a signal y1received by a second antenna; these are synthesized to determine a synthesized estimate value ΔlnP0(I). Further, a first bit estimate value for a second data stream is determined from a signal received by the first antenna, and bit a second estimate value for the second data stream is determined from a signal received by the second antenna; these bit estimate values are synthesized to determine a synthesized estimate ΔlnP1(I). The bit estimate value of the first data stream is refined using the synthesized estimate value of the second data stream, and based on the synthesized estimate value for the first data stream, “0” or “1” of the bit is decided for the first data stream.
