摘要：Systems and methodologies are described that facilitate improved pilot
information to MIMO user devices without increasing interference of SISO user devices ina wireless communication environment. A data communication signal can be generatedand transmitted at a first power level, and a continuous pilot waveform comprising pilotinformation related to the data signal can be generated and sent at a second power levelbelow the first transmission power level. Alternatively, a discontinuous pilot waveformcan be generated so that it does not overlap with pilot segments in the first waveform,and can be transmitted at the first power level without interfering with the first waveformas received by a SISO user device. A MIMO user device can receive both waveforms, andcan employ the pilot waveform to better estimate a MIMO channel for the firstwaveform.
