摘要：
A receiver of digital data bursts is provided comprising an antenna array (A), a first space time filter (26) having filter coefficients initialised by estimation over just training data in a received burst (LST) and providing symbol estimates and a second space time filter (28) having filter coefficients initialised by estimation over the received burst (LSB) and providing symbol estimates. In use at least one pass to determine a symbol estimate in the received burst is undertaken by each space time filter and a selector (24) operates to determine which of the first and second filters provides the symbol estimate closer to an expected value.
