| Abstract(in English) | This paper investigates the optimum structures for the primary and non-primary broadcast channel (BCH) that take advantage of the respective BCH information for the OFDM based Evolved UTRA downlink. In the proposed structure, the BCH is transmitted from the central part of the system bandwidth in each cell regardless of the transmission bandwidth. The primary BCH is transmitted with a 1.25-MHz bandwidth to simplify the cell search operation at the user equipment (UE) where time diversity with soft-combining is applied. The non-primary BCH is transmitted with a wide transmission bandwidth such as 5 or 10MHz to achieve a large frequency diversity effect. Simulation results show that the primary and non-primary BCHs achieve almost the same average received E_s/N_0 (signal energy per symbol-to-noise power spectrum density ratio) to reach the average packet error rate of 10^<-2> by taking advantage of time diversity and frequency diversity, respectively, under low mobility conditions with the fading maximum Doppler frequency of 5.55Hz. |
