Random access transport capacity
Abstract--We develop a new metric for quantifying end-toend throughput in multihop wireless networks, which we term random access transport capacity, since the interference model p...

Achievable rates for cognitive radios opportunistically permitting excessive secondary-to-primary interference
Abstract--We propose a cognitive radio system in fading environments where the secondary sender opportunistically violates the secondary-to-primary (S-P) interference power limit. ...

A Novel Graph-Based Suboptimal Multiuser Detector for FDM-CPM Transmissions
We consider a frequency division multiplexed (FDM) system where each user employs a continuous phase modulation (CPM), serially concatenated with an outer code through an interleav...

A PAPR Reduction Method Based on Artificial Bee Colony Algorithm for OFDM Signals
Abstract--One of the major drawbacks of orthogonal frequency division multiplexing (OFDM) signals is the high peak to average power ratio (PAPR) of the transmitted signal. Many PAP...
