Modern wireless device have sleep mode which greatly reduce the duty cycle of the power supply.Consider the effect of different duty cycles and transmit times to see the wide range of battery lifetimes one may expect before recharging.
results is being plotted of battery lifetime as a function of the duty cycles & duration of the wake up mode.

EWA
Earthworms can aerate the soil with their burrowing action and enrich the soil with their waste nutrients. Inspired by the earthworm contribution in nature, a new kind of bio-inspired metaheuristic algorithm, called earthworm optimization algorithm (EWA), is proposed in this paper. The EWA method is inspired by the two kinds of reproduction (Reproduction 1 and Reproduction 2) of the earthworms. Reproduction 1 generates only one offspring by itself. Reproduction 2 is to generate one or more than one offspring at one time, and this can successfully done by nine improved crossover operators. In addition, Cauchy mutation (CM) is added to EWA method. Nine different EWA methods with one, two and three offsprings based on nine improved crossover operators are respectively proposed. The results show that EWA23 performs the best and it can find the better fitness on most benchmarks than others.

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀(CP)可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是,过长CP会使得数据传输效率降低。可以采用最小均方误差(MMSE)信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)
