How to create independent channels needed for diversity? Frequency diversity time diversity space diversity 5 why transmit diversity? In downlink, receive diversity is difficult to implement requires multiple antennas and additional processing at the mobile station not suitable due to size and battery power limitation at mobile put additional processing and complexity at the base station transmit diversity 6 transmit diversity close loop transmit diversity requires feedback of channel from the receiver to the transmitter open loop transmit diversity no need for feedback ex delay diversity an ancestor of space-time trellis codes.
