Hi
I red this phrase regarding beam forming in Wimax
"To perform transmit beamforming, the transmitter needs to have accurate knowledge
of the channel, which in the case of TDD is easily available owing to channel reciprocity but for FDD requires a feedback channel to learn the channel characteristics."
What's meant by channel reciprocity?
And how it could be used for channel estimation?
