Abstract

In this paper, we propose a new homogeneous burst structure for the time-division duplex (TDD) component of the universal mobile telecommunication system (UMTS). The midamble period is removed and replaced by a data field to enhance the system's spectrum efficiency. Alternatively, a pilot signal is loaded into one of these bursts over each time slot, in order to ensure a continuous channel tracking by means of a pilot-assisted adaptation. Computer simulations are used to assess the performance of the adaptation strategy over the proposed time burst.
