Capacity analysis of a decode-and-forward cooperative network under adaptive transmission
—This paper presents a capacity analysis of a decode-and-forward (DF) cooperative network with adaptive source transmission. Three different adaptive techniques are considered: (i) optimal simultaneous power and rate adaptation (OPRA); (ii) constant power with optimal rate adaptation (ORA); (iii) truncated channel inversion with fixed rate (TIFR). Closed form capacity expressions are derived for non-identical and independently distributed (non-i.i.d.) Nakagami-m fading wireless environments. These expressions are validated by simulation results obtained through Monte Carlo simulation. It is observed that OPRA and ORA provide roughly the same capacity, while TIFR yields slightly less capacity relative to the other two.
