摘要： In a wireless system, a method and system for channel estimation in a single channel MIMO system comprising two-transmit and multiple-receive antennas for WCDMA/HSDPA are provided. A first receive antenna and at least one additional receive antenna may receive a plurality of SC communication signals transmitted from a first and an additional transmit antennas. Estimates of the propagation channels between transmit and receive antennas may be performed concurrently and may be determined from a baseband combined channel estimate. The integration time may be based on channel estimation accuracy and wireless modem performance. The signals received in the additional receive antennas may be multiplied by a rotation waveform to achieve channel orthogonality. The rotation waveform's amplitude and phase components may be modified based on the channel estimates. Rotation of the received signals in the additional receive antennas may be continuous or periodic.

摘要： In wireless systems, a method and system for pre-equalization in a single weight (SW) single channel (SC) multiple-input multiple-output (MIMO) system are provided. A first receive antenna and at least one additional receive antenna may receive a plurality of SC communication signals transmitted from at least two transmit antennas. Estimates of the propagation channels between transmit and receive antennas may be performed concurrently and may be determined from baseband combined channel estimates. Channel weights may be determined to modify the signals received by the additional receive antennas. Pre-equalization weight parameters may be determined to modify subsequent signals transmitted from the transmit antennas. The pre-equalization weight parameters may be based on the propagation channel estimates and may be determined by LMS, RLS, DMI, or by minimizing a cost function. Closed loop transmit diversity may also be supported.
