Another powerful approach is to use space-time BICM: the data is encoded with a convolutional code, then interleaved, distributed to the transmitter antennas, modulated into complex symbols and transmitted (Figure ). Then, assuming a block fading channel such that a channel realization H is constant for a block duration of T seconds but changes independently every T seconds, we define a resource allocation policy as a power allocation procedure that every T seconds maps a new channel realization H to a power allocation vector p (H) = { p1,pk }.

We consider the optimal precoder design with the assumption that the transmitter only has channel covariance information, for the multi-input multi-output (MIMO) information and energy transmission system.

Previous work on limited feedback space-time coding has focused primarily on the case where the linear precoding matrix chooses subsets of the available transmit antennas [14], [15], [23]–[25]. Performance improves, however, by allowing the space-time code’s linear precoding matrix to have a more general form [10], [11], [13], [26], [27].

unknown, an Orthogonal Space-Time Block Coding (OSTBC) scheme can be employed [5]. In [6] Jo¨ngren proposed a scheme that computes the optimal linear combination between beamforming and OSTBC based on the quality of the channel estimate.

While an optimal scheme, for a fast moving channel this scheme would become prohibitively complex since for. mission scheme, e.g. beamforming, orthogonal space-time block codes (oSTBCs) and linear dispersion (LD) codes [1]; and the form of feedback, e.g.

perfect feedback, statistical feedback, and lim-ited (channel state) feedback. There has been substantial research on feedback schemes for beamforming and orthogonal space-time. In mobile scenarios, the channel may be quickly varying, and covariance feedback becomes an adequate approach to adopt as the channel statistics do not vary quickly.

In this paper, we consider the problem of transmit beamforming design for MIMO-OFDM systems when the covariance matrix of the channel is available at the transmitter. 3blue1brown, by Grant Sanderson, is some combination of math and entertainment, depending on your disposition.
