Abstract:
A transmission apparatus maps a first stream of input data to first complex symbols in serial format and convert them into first complex symbols in parallel format. They are inverse Fourier transformed into OFDM signals associated with multiple subcarriers that are transmitted via a first antenna over the multiple subcarriers in a same frequency band over a same time period that includes a same set of time slots. First pilot information is transmitted via a first antenna on a first one of a plurality of pilot subcarriers during the same set of time slots, and second pilot information is sent via a first antenna on a second one of a plurality of pilot subcarriers during the same set of time slots. The second pilot information is different from the first pilot information. A second stream of input data is similarly transformed to form second OFDM signals transmit via a second antenna over the multiple subcarriers in the same frequency band over the same time period that includes the same set of time slots. The first pilot information is transmitted via the second antenna on the second pilot subcarrier during the set of same time slots, and the second pilot information is transmitted on one of the pilot subcarriers during the same set of time slots.

Claim (Index 1):
A transmission apparatus comprising:\n electronic circuitry to:\n map a first stream of input data to first complex symbols in serial format; \n convert the first complex symbols in serial format into first complex symbols in parallel format; \n perform an inverse Fourier transform on the first complex symbols in parallel format to form first Orthogonal Frequency Division Multiplexed (OFDM) signals associated with multiple subcarriers; \n transmit the first OFDM signals via a first antenna over the multiple subcarriers in a same frequency band over a same time period that includes a same set of time slots; \n transmit first pilot information via a first antenna on a first one of a plurality of pilot subcarriers during the same set of time slots; \n transmit second pilot information via a first antenna on a second one of a plurality of pilot subcarriers during the same set of time slots, the second pilot information being different from the first pilot information; \n map a second stream of input data to second complex symbols in serial format; \n convert the second complex symbols in serial format into second complex symbols in parallel format; \n perform an inverse Fourier transform on the second complex symbols in parallel format to form second OFDM signals associated with the multiple subcarriers; \n transmit the second OFDM signals via a second antenna over the multiple subcarriers in the same frequency band over the same time period that includes the same set of time slots, \n transmit the first pilot information via the second antenna on the second pilot subcarrier during the same set of time slots; and \n transmit the second pilot information on one of the plurality of pilot subcarriers during the same set of time slots.
