This is an investigated research article on resource block scheduling of Long Term Evolution (LTE). LTE is one of the evolutions of the Universal Mobile Telecommunication System (UMTS). It provides internet access to mobile users through smart phone, laptop and other android devices. LTE offers a high speed data and multimedia services. It supports data(More)
BACKGROUND Food shortage was associated with leprosy in two recent studies investigating the relation between socioeconomic factors and leprosy. Inadequate intake of nutrients due to food shortage may affect the immune system and influence the progression of infection to clinical leprosy. We aimed to identify possible differences in dietary intake between(More)

In static cognitive radio network a secondary transmitter communicates directly with a secondary receiver only when the spectrum is not occupied by any primary user. The secondary user has to stop its transmission when no spectrum holes exist. To improve the transmission capacity, in this paper we approach to combine cognitive radio network with cooperative(More)
— We investigate the performance of uncoded uplink transmissions in a broadband code division multiple access (CDMA) system using a tapped delay line (TDL) antenna array. First, the weights of a TDL antenna array are derived for broadband CDMA. Using these weights, we perform simulations to demonstration how TDL antenna arrays can help reduce multi-access(More)
CDMA refers to multiple access method in which the individual terminals uses spread spectrum techniques and occupy the entire spectrum whenever they transmit. This feature makes CDMA different from FDMA and TDMA. In the wireless communication, the Signal to Interference Ratio (SIR) and Bit Error Rate (BER) are the predominant parameter that characterizes(More)
