Coding-Spreading Tradeoff for Lattice Codes
A fixed bandwidth expansion can be achieved either by coding or spreading, while each have different effect on the resultant signal space. Coding increases both Shannon and Fourier bandwidth whereas spreading only increases ...
Signal and Information Processing for Wireless Communication Systems
Next generation wireless communication systems need to support access to multimedia data available on the internet. This universal wireless access to multimedia data requires data rates and quality of service that are ...
On Multipath Channel Estimation for CDMA Systems Using Multiple Sensors
This paper focuses on the design of a multiuser receiver structure for the reverse link of a code-division multiple-access communication system, in the presence of multipath effects and using an antenna array at the base ...
