The performance of the algorithm in terms of WDO is only reduced by 4% in the case of transmitting 64 kbps, 17% in the case of transmitting 8 kbps, and 25% in the case of transmitting only 2 kbps, which are feasible bit rates for hearing aids.
During the n th iteration, if all the feasible bits are transmitted by the i th epoch for ∃i ∈ {1,2,...,k n }, then the Flag is set to i (Flag < i).
Illustration of the Flag and local optimizations, where all the feasible bits have been transmitted until the end of the fifth epoch; hence, a Flag is set to the fifth epoch pair, i.e., Equations 4 and 5. Energy minimization is performed upto epoch pair with the Flag, and time minimization is performed for the rest.
It cannot stay constant until T opt, because it contradicts the fact that S opt transmits all the feasible bits before T opt, i.e., ∑ i = 1 s + m ( r 1 i D u − r 1 i opt ) ξ i > 0. Since the strong user's rate in S opt cannot decrease by Lemma 4, it should increase at the end of epoch (k + n) for 0 ≤ n < (s + m − k), i.e., r 1 ( k + n ) opt < r 1 ( k + n + 1 ) opt.
Given the SINR γ and assuming uniform PA across the subcarriers1, first the BL procedure originally proposed in [37] is applied, with the set of feasible number of bits per subcarrier being {0,m}.
Thus a graceful degradation of sound quality with bit rate should be feasible.
Desirably, one or two additional bits are sufficient to enable TN-SDMA with a feasible number of antennas c to achieve the PU2RC throughput.
Feasible Throughput: A throughput of λ(n) bits per second for each node is feasible if every node can send λ(n) bits per second on average to its destination.
In a TDMA standard such as DECT, low bit-rate transmission is feasible either at the cost of efficiency (shorter slots with fixed overhead per slot) or increased latency (longer frames).
Going back a bit, H.W. Fowler didn't like "feasible" in the first place (considering it needlessly fancy in his 1926 "Modern English Usaage"), but the Concise Oxford Dictionary (1911) that he co-edited lists "unfeasible" (not "infeasible").So experts disagree and for once, the OED seems to be wrong.
