With recent advancements in Software Defined Radio technology the usage of partially overlapping carriers (POCs) has become a viable option to better utilize available spectrum resources. Thus the need has surfaced to truly understand the impact of POCs on system performance. In this paper, we first propose a generalized spectrum channelization(More)
Cyclic Redundancy Checks (CRCs) are extensively used for effective error detection in communication systems. Previous studies evaluate the performance of CRC generator polynomials solely based on their Undetectable Error (UE) criterion without taking retransmission and overhead dynamics into account. In this paper, we study CRC coding performance by(More)

Channel estimation and tracking methods are very critical parts of wireless Orthogonal Frequency Division Multiplexing (OFDM) systems in time and frequency selective communication channels. Interpolation has been popularly used in both domains when the channel is sampled with pilot subcarriers. The classical approach is to use the Least Square (LS)(More)
This paper presents a novel classification/retrieval system for motion events based on a perfect view invariant representation of motion trajectories and a linear classifier algorithm. Specifically, Null Space Invariant (NSI) matrix representation for motion trajectories has been derived. The proposed view invariant representation based on the NSI operator(More)
