    摘要: The present invention provides a versatile system for optimizing pilot pattern diversity in a digital communications system—particularly in multiple antenna OFDM communications systems. According to the present invention, a receiving device within a communications system may receive transmissions from a first transmitting device (202) and a second transmitting device (204), on a single tone (214, 216) within a given time segment (206-212). The first transmitting device transmits a first pilot pattern to the receiving device on the tone. A differentiation scheme (200) is provided and utilized to transform a second pilot pattern from the second transmitting device, and the transformed second pilot pattern is transmitted to the receiving device on the tone.
