Journal Article
Yahya, M. A., Alsaif, O. I., Saleh, I. A., Abdulkhaleq, A. M., Ojaroudi Parchin, N., Al-Yasir, Y. I. A., & Abd-Alhameed, R. A. (2019). Noise Cancellation for HIPERLAN/2 with Open Loop Transmit Diversity Technique. Inventions, 4(3), Article 46. https://doi

A new proposed method is presented, where multiple antennas have been applied into HIPERLAN/2 system in addition to employing space-time diversity technique, especially the Alamouti technique. The suggested approach is used to cancel or reduce the ef... Read More about Noise Cancellation for HIPERLAN/2 with Open Loop Transmit Diversity Technique.
