This paper proposes a group version of the nearest neighbor (NN) query, called the nearest neighborhood (NNH) query, which aims to find the nearest group of points, instead of one nearest point. Given a set O of points, a query point q, and a ρ-radius circle C, the NNH query returns the nearest placement of C to q such that there are at least k points enclosed by C. We present a fast algorithm for...
The capacity of feedback links is typically limited and shared by multiple users. So this paper studies the impacts on multiple input multiple output (MIMO) broadcast channel (BC) when limited feedback capacity is shared among multiple users. Our mathematical analysis proves that in the high signal-to-noise ration (SNR) region, allocating the whole feedback capacity to a single user is the optimal...
