“…In case of multicarrier transmission, approximating the channel-transfer function by a staircase function (see Fig. 3) and summing over all tones/carriers, one finds that the total bit rate is given as [18], [19] ( 8) where is the number of carriers, and 's are such that (9) Assume that the symbol-error rate for each of the tones/carriers is the same, and equal to . We also use instead of ; hence, or will lower bound or upper bound the transmission bit rate.…”

Abstract-In this paper, we report theoretical and experimental channel-capacity estimates of heating, ventilation, and air conditioning (HVAC) ducts based on multicarrier transmission that uses -ary quadrature amplitude modulation and measured channel responses at the 2.4-GHz industrial, scientific, and medical band. It is shown theoretically that data rates in excess of 1 Gb/s are possible over distances up to 500 m in straight ducts in which reflections have been suppressed. Our experimental results also show that even in the case of more complex HVAC duct networks (i.e., HVAC duct networks that include bends, tees, etc.) data rates over 2 Gb/s are possible. Our estimations in this case are valid for distances of up to 22 m, which was the maximum distance of our experimental setup. These experimental results, measured with a large-scale testbed set up at Carnegie Mellon University, Pittsburgh, PA, albeit limited in terms of transmitter-receiver separation distance, provide further evidence on the potential of HVAC systems as an attractive solution for providing communications in indoor wireless networks.Index Terms-Heating, ventilation, and air conditioning (HVAC) systems for wireless transmission, indoor propagation, internet access, multicarrier transmission, orthogonal frequency-division multiplexing (OFDM).

SUMMARYUp-and downlink transmission over multiple-input/multiple-output (MIMO) channels where the transmission paths exhibit intersymbol interference (ISI) are studied. Equalisation schemes for multipointto-point scenarios (multiple access problem, uplink) and precoding schemes for point-to-multipoint scenarios (broadcast channel (BC), downlink) are investigated. In particular, singlecarrier modulation employing decision-feedback equalisation (DFE)/precoding, multicarrier (MC) modulation employing BLAST/precoding per carrier and frequency-division multiplexing (FDM) in disjoint frequency bands are considered. The rate regions, that is the region of admissible rates of the users, for these approaches are given and compared. It is shown, that despite single-and multicarrier transmission can achieve the same sum rate, in each case MIMO OFDM offers the largest rate region. The results are illustrated via numerical examples.
