Transmitting a data signal employing a digital beamforming technique including determining a first phase offset in response to a first transmitted signal received at a first antenna and a second phase offset in response to a second transmitted signal received at the first antenna, determining a third phase offset in response to the first transmitted signal received at a second antenna and a fourth phase offset in response to the second transmitted signal received at the second antenna, generating a first correction weight in response to an average of the first phase offset and the third phase offset, generating a second correction weight in response to an average of the second phase offset and the fourth phase offset, and transmitting the first correction weight to the first transmitter and the second correction weight to the second transmitter.

Error correction in a distributed beamforming

Transmitting a data signal by generating a first symbol in response to the data signal and a first synchronization sequence and a second symbol in response to the data signal and a second synchronization sequence, applying a distributed coding matrix to the first symbol and the second symbol to generate a first transmission signal and a second transmission signal, transmitting the first transmission signal and the second transmission signal to the far field, isolating the first transmission signal by applying the first synchronization sequence to the far field, isolating the second transmission signal by applying the second synchronization sequence to the far field, applying the distributed coding matrix to the first transmission signal to extract the first symbol, applying the distributed coding matrix to the second transmission signal to extract the second symbol and estimating the data signal in response to the first symbol and the second symbol.
