Performance of adaptive equalization for indoor radio communications

Adaptive equalization is used to ensure that the outage probability is less than 10/sup -3/ for a target bit error rate of 10/sup -4/ in buildings with RMS delay spread of up to 100 ns. A time-division multiple-access system with four-level quadrature amplitude modulation point-to-point links strikes the right balance between flexibility and complexity. It is shown that such a system can support rates of at least 1 Mb/s.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
