Software

We have two testbed implementations: (i) FATCAPS base station, and (ii) integrated base station. The former one is based on FATCAPS implementation, while the later one is implemented by us from scratch.

FATCAPS Based Implementation

• Media FLO Technology

• Q. Gao, M. Chari, A. Chen, F. Ling, and K. Walker, "MediaFLO Technology: FLO Air Interface Overview": This book chapter explains why mediaFLO achieves short channel switching delay. MediaFLO employs 1-sec superframe and each MLC is transmitted as four bursts in every superframe. Therefore, when user switches the channel in superframe x, the receiver will get all the four bursts in superframe x+1, which takes 1 to 2 secs, where 1 is the best case and 2 is the worst case. This article also indicates that the time-frequency assignment need not be rectangle, which allows finer grained resource allocation and thus better statistical multiplexing gain. However, this paper does not address the relationship between energy saving and time-freq allocation. There is only one sentence saying that the receiving circuit should avoid modulating the symbols irrelevant to the current channel to save energy.
