We propose a framework for designing an underlay secondary CDMA network. The objective is to select the secondary system's bit rate and spreading factor that improve the secondary network throughput given a required bit error rate and an allowable transmit power level acceptable to the primary network. The selection scheme is applied to both the case of(More)
The growing energy consumption of communication systems raises economical and environmental concerns. Indoor visible light communication (VLC) systems are energy friendly as they exploit the illumination power of LED luminaries for data transmission. However, the VLC systems suffer from service disruptions due to the limited coverage of light. To alleviate(More)
