A novel joint channel estimation and partial parallel interference cancellation (JCPPIC) receiver is proposed in the up-link pilot-assisted CDMA (code division multiple access system), where the transmitted pilot symbols are followed by information data symbols in each time slot of each user. In the JCPPIC receiver, the joint iterative structure is utilized to deal with the inaccurate reception problem...
This paper concerns the cross-layer design between physical layer and MAC (multiple access control) layer in asynchronous wireless random access network. The proposed cross-layer design consists of two parts: a MPR (Multiple Packet Reception) physical layer and a collision- aware MAC layer. In the physical layer design, different spreading codes are assigned to packets according to their frame types...
