— Frequency domain equalization has gained a lot of attention in the last decade, mainly pushed by the OFDM (Orthogonal Frequency Division Multiplexing) communication scheme. It has been adopted, in various flavours, for, among others, Wireless Lans and xDSL. The technique is indeed leading to low complexity implementation, at the cost of a Cyclic Prefix ,(More)
This paper gives an overview of results of the Human++ research program [1]. This research aims to achieve highly miniaturized and nearly autonomous sensor systems that assist our health and comfort.

— Orthogonal Frequency-Division Multiplexing (OFDM) with cyclic prefix enables low cost frequency-domain mitigation of multipath distortion. However, to determine the equalizer coefficients, knowledge of the channel frequency response is required. While a straightforward approach is to measure the response to a known pilot symbol sequence, existing(More)
This paper gives an overview of the results of IMEC's Human++ research program [1]. This program aims to achieve highly miniaturized and autonomous sensor systems that enable people to carry their personal body area network. The body area network will provide medical, lifestyle, assisted living, sports or entertainment functions. It combines expertise in(More)
