Abstract
A communications circuit can operate in a first mode, such as a diversity mode including space time transmit diversity (STTD). In this mode, a number of equalizer filter portions connected to a number of post-equalizer processors are employed. When the diversity mode is not required, the extra equalizer filter portions would represent a waste of power consumption and/or chip space. A combining circuit and suitable control circuitry are provided to allow use of the additional equalizer filter portions to be made in other operating modes. Appropriate trade-offs can be made based on power consumption and performance.
