Methods and apparatus for estimating code-reuse interference associated with a received multi-stream multiple-input multiple-output (MIMO) signal of the D-TxAA type, are disclosed. In an exemplary method, impairment covariance associated with the received multi-stream MIMO signal is measured (510), and first and second sets of samples for received traffic data symbols are collected (520, 530), using first and second sets of RAKE 'combining weights corresponding to effective net channel responses for first and second streams of the multi-stream MIMO signal, respectively. A per-code energy value for at least one stream of the received multi-stream MIMO signal is computed (550), as a function of the measured impairment covariance, the effective net channel responses for the first and second streams, and the first and second sets of samples. Finally, code-reuse interference associated with the first stream is calculated (560), as a function of the per-code energy value and the effective net channel response corresponding to the first stream. |
