Abstract
A time-varying transformation is used to correlate the magnitude of the interference between multiple antenna paths. Embodiments incorporating the time-varying transformations provide transmit diversity gains to remote stations that are not configured for transmit diversity reception. In addition, some of the embodiments can be further configured to balance the load between multiple power amplifiers.
Claims1
A redistribution unit for processing a primary transmission signal and an auxiliary transmission signal within a transmission diversity system to provide transmission diversity gains to non-transmission diversity receivers, comprising:
- a first time-varying element for generating a time-varying copy of a primary transmission signal and redistributing the time-varying copy of the primary transmission signal to an auxiliary-antenna;
- and
- a second time-varying element for generating a time-varying copy of the auxiliary transmission signal and for redistributing the time-varying copy of the auxiliary transmission signal to the auxiliary antenna.
