Scaling the number of cores on processor chips has become the trend for current semiconduction industry (i.e. Intel/AMD many-core CPU, Nvida GPU etc). Current software development should take advantage of those multi-core platforms to achieve high performance. But it is a challenging task to develop parallel software on multiple processor because of the well known problems such as deadlock, load balancing,...
OFDM (orthogonal frequency division multiplex) mobile communication system is so popular in recent because it has so many virtues as effective frequency spectrum, wide-band, high speed rate, etc. But it has so many challenges in technical field, such as the high efficiency of PA (power amplifier) and linearity. RF (radio frequency) amplifier with ET (envelop-tracing) structure is described for OFDM...
