Modern mobile telecommunication systems, such as 3GPP LTE, make use of Hybrid Automatic Repeat reQuest (HARQ) for efficient and reliable communication between base stationsand mobile terminals. To this purpose, marginal posterior probabilities of the received bits are stored in the form of log-likelihood ratios (LLR) in order to combine information sent(More)
This work studies linear transmit filter design to maximize weighted sum-rate for the Multiple Input Multiple Output Broadcast Channel (MIMO-BC). In a recent result, it was shown that the derivative of mutual-information is equal to the Minimum Mean Square Error (MMSE) for the single-user case. This paper derives a relation between weighted sum-rate and(More)
