Expander Graph Based Overlapped Chunked Codes
Expander Graph Based Overlapped Chunked Codes
2012/12/4
Chunked codes are a variation of random linear network codes with low computational complexities. In chunked codes, the packets in a file are grouped into small (non-overlapped or overlapped) chunks, ...
Optimization Framework and Graph-Based Approach for Relay-Assisted Bidirectional OFDMA Cellular Networks
Optimization Framework Graph-Based Approach OFDMA Cellular Networks
2010/11/29
This paper considers a relay-assisted bidirectional cellular network where the base station (BS)communicates with each mobile station (MS) using OFDMA for both uplink and downlink. The goal is to impr...
