Patent ID: 8311492

Claim:
A system for diversity transmission, the system comprising: a base station, comprising: a first channelization device to receive data and spread the data with a first channelization code to produce a first spread data field, and wherein the first channelization code is utilized exclusively for transmission on the first antenna; a second channelization device to receive the same data as the first channelization device and spread the received data with a second channelization code that is different from the first channelization code to produce a second spread data field, and wherein the second channelization code is utilized exclusively for transmission on the second antenna; a first training sequence device in communication with the first channelization device, the first training sequence device to combine the first spread data field with a first midamble to produce a first communication burst, the first midamble for estimating a channel impulse response; a second training sequence device in communication with the second channelization device, the second training sequence device to combine the second spread data field with a second midamble to produce a second communication burst, the second midamble for estimating a channel impulse response; a first scrambling device to scramble the first spread data field by a scrambling code associated with the base station; a second scrambling device to scramble the second spread data field by the scrambling code associated with the base station; a first diversity antenna to transmit the first communication burst; and a second diversity antenna to transmit the second communication burst; and a user equipment, comprising: a data detection device having an input configured to receive the signal being diversity transmitted, the received signal having the first communication burst and the second communication burst, the first and second communication bursts being transmitted from the same base station in a same time slot over different antennas and the first and second communication bursts having the same data in a same order, each of the first and second communication bursts having the inserted midamble training sequence used for estimating a channel impulse response, and a scrambling code associated with a transmitting base station, the data detection device configured to process the received signal with the first channelization code associated with the first transmission antenna to produce first data and the data detection device configured to process the received signal with the second channelization associated with the second transmission antenna to produce second data, wherein the first and second data are the same data.
