Abstract: This invention relates to a method of manufacturing a DRAM cell which has a stacked capacitor and forming drain and source polycrystalline silicon regions on surface of a semiconductor substrate. The invention is directed to: a first step for forming a field oxide film and channel stopper as well as a polycrystalline silicon oxide film doped with impurities; a second step for dividing said silicon into a drain and source polycrystalline silicon region and forming a gate oxide film between the two silicon regions simultaneously with the drain and source diffusion regions and a gate electrode on the gate nitride film; a third step for forming an insulating film on the upper surface of the nitride film and a window on the source polycrystalline silicon region, a storage poly contacting with the same through the window; a fourth step for forming a dielectric layer and a plate poly of the stacked capacitor; and a fifth step forming another insulating film thereon and forming a window on the drain polycrystalline silicon region and also forming a bit line contacting with the exposed drain polycrystalline silicon region through that window. This invention can prevent the generation of leakage current resulting from the damage caused by the drain and source diffusion polycrystalline silicon regions when an etching process is used for the formation of the storage poly and the bit line.

Abstract: Systems and methods for detecting unused channels in a cognitive radio system are described. In one method, data is communicated on a particular channel for a secondary receiver. In addition, a set of channels is iteratively scanned by collecting samples for each channel and for each iteration of the scanning. Here, iterations of the scanning progressively removes channels from the set of channels based on the collected samples and updates states of the channels in the set based on the collected samples to obtain a set of candidate channels. In response to detecting a pre-determined condition, communications on the particular channel are precluded and at least one of the candidate channels is evaluated by collecting additional samples on each of the channels. Further, at least one of the candidate channels is selected based on the evaluation for utilization by the one or more secondary receivers for data communication.

Abstract: Spectrum sensing methods and systems for detecting spectrum holes for use in cognitive radio secondary transmissions are disclosed. In one method, an indication of an assignment of a set of subcarriers to a primary user is received. The method further includes determining multitaper spectral estimates for at least a subset of the set of subcarriers based on the assignment of the set of subcarriers to the primary user by processing samples for the at least a subset of the set of subcarriers. In addition, a test statistic that is based on the multitaper spectral estimates is compared to a threshold to determine whether the set of subcarriers is utilized for primary transmissions to the primary user. Moreover, data signals are received on at least one of the subcarriers in the set of subcarriers if the set of subcarriers is not utilized for primary transmissions to the primary user.
