Venue: EM 2.33
Name: Prof. Hsiao-Hua Chen, Institute of Communications Engineering, National Sun Yat-Sen University, Taiwan.
This talk will review our ongoing research activities on time-frequency two-dimensional CDMA coding. In particular, we will propose a new CDMA code design methodology, namely Real Environment Adapted Linearization (REAL) approach, which can generate CDMA code sets with inherent immunity against multipath interference and multiple access interference for both up-link and down-link transmissions. It will also be shown that an interference-free CDMA can only be implemented using orthogonal complementary code (OCCs). Several other issues on the OCC-CDMA, such as its system implementation and performance, will also be addressed.
