Space complexity of hierarchical heavy hitters in multi-dimensional data streams
Heavy hitters, which are items occurring with frequency above a given threshold, are an important aggregation and summary tool when processing data streams or data warehouses. Hie...

Weighted maximum likelihood autoregressive and moving average spectrum modeling
We propose new algorithms for estimating autoregressive (AR), moving average (MA), and ARMA models in the spectral domain. These algorithms are derived from a maximum likelihood a...

A Post-Detection SNR-Aided Timing Recovery Loop for MIMO-OFDM Receivers
--- In this paper, a novel third-order Phase Lock Loop (PLL) is proposed for the timing recovery in MIMO-OFDM systems. It differentiates from conventional timing recovery algorithm...
