We consider a flashy transmission scheme in multiple-input single-output (MISO) systems. In order to efficiently utilize the limited energy budget, only a portion of the available time is used for the actual transmission. For block-wise transmissions, we define the flashiness as the percentage of blocks used for the actual transmission. Each transmission block consists of a reverse training phase...
In Multiple Input Multiple Output (MIMO) systems, predicting performance prior to data transmission is needed to appropriately select transmitter parameters (e.g. power, code rate). The prediction must be both accurate and easy to compute, given limited resources. An algorithm taking too much time to run or excessive circuitry to implement cannot be deployed. This paper presents an algorithm to predict...
We consider the problem of precoding optimization for wireless MIMO nodes that are assigned both to serve its own destination and to relay another data transmission with a different destination. Unlike the traditional MIMO relay broadcast model, our cooperative node not only amplifies and relays another source signal to its destination but also sends its own information to another destination. Our...
In a two-way system where two users transmit data to each other, limited feedback beamforming is a simple method to supply channel state information to the transmitter (CSIT) for a multiple-input-multiple-output (MIMO) system when channel reciprocity is unavailable. For analytical tractability, most existing papers assume the existence of an ideal fixed-rate feedback channel to assist the transmitter...
