    • Bandwidth efficiency of W/V--band channel using DVB-S2 adaptive code modulation 

      Lahman, Richard T. (Wichita State University, 2020-07)
      Here we study bandwidth efficiency by understanding the relationship between signal attenuation and adaptive code modulation (ACM) schemes in Digital Video Broadcasting-Satellite Second Generation (DVB-S2). Then we apply ...
    • Conversion from channel attenuation to data rate estimation 

      Lahman, Richard T.; Hulede, Ian Ellis L.; Kwon, Hyuck M.; Murrell, David A.; Lane, Steven A. (IEEE, 2021-03-06)
      In an early development state for a wireless terrestrial or satellite communication system, channel path attenuation data is typically collected first under an additive white Gaussian noise (AWGN) in the line of sight by ...
    • An optimal approach for maximizing the sum rate 

      Lahman, Richard T.; Odeyomi, Olusola T.; Kwon, Hyuck M.; Murrell, David A. (IEEE, 2021-03-06)
      This paper considers a different approach from the conventional way of maximizing sum rate where the bandwidth is always assumed to be shared evenly among users in a power-constrained single-input single-output (SISO) ...
