Kevin Yu , Sriram Vishwanath Several projects in the Wireless Systems Lab are also studying turbo codes both as a topic in itself and also in conjunction with other system issues.
Current research involves bounds for predicting the performance of turbo coded modulation systems.
These bounds enable the study of adaptive turbo coded modulation. Space-time turbo codes are also being examined. Turbo coded modulation can be combined with many existing systems issues such as non-linear modulation and intersymbol interference. Syed Ali Jafar Multirate DS-CDMA dominates the third generation wireless communications standards. With new applications coming up, each with its own Quality of Service requirements, the need to support multiple data rates and a very diverse traffic distribution across users demands more sophisticated schemes to achieve high spectral efficiency.
