摘要： Transmission quality is improved in an environment in which direct waves dominate in a transmission method for transmitting a plurality of modulated signals from a plurality of antennas at the same time. All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.

摘要： A receiver for demodulating wireless signal using multiple receive antennas includes multiple signal detection modules, with each module implementing a non-interference rejection combining signal detection technique. The receiver makes a decision about whether or not to use an interference rejection combining technique, and which signal detection module to use based on the operating conditions of the received signals. When the decision is made to use an interference rejection combining technique, a single whitening filter is used to whiten the received signal prior to sending the whitened signal for processing by the signal detection module. The whitening filter may be calculated as a Cholesky decomposition of an impairment covariance matrix generated from the signals received at the multiple antennas.

摘要： A power-allocation method for scalable video transmission over MIMO system includes: encoding a video sequence into L layers; performing MCSs to the layers and estimating bit error rate or symbol error rate respectively for each of the layers after MCSs procedure based on channel quality feedbacks from the receiver side; performing power allocations of L sub-problems and obtaining candidate power allocation solution of each of the sub-problems respectively based on bit error rate or symbol error rate of each of the layers and derivative of bit error rate or symbol error rate of each of the layers; and choosing one of the candidate power allocation solution with the largest quality of experiences as the power allocation of the scalable video transmission over MIMO system. This invention considers transmission-error-rate of PHY layer and video coding structure of APP layer and optimizes quality of experiences at user end with cross-layer design.
