The simplest model that is frequently used for a transmission channel is the additive white Gaussian noise (AWGN) channel model. In this model the received signal is the sum of the transmitted signal and Gaussian noise. The simple channel model has great theoretical and practical importance and is an accurate...

Trellis coded modulation (TCM) formats with their excellent bandwidth and power efficiency have been widely employed in various communication systems. For mobile satellite communications, trellis coded (TC) M-ary phase shift keying (MPSK) is the primary candidate modulation technique. In the first generation mobile satellite systems, co-channel interference (CCI) does not...

Untuk memperluas jangkauan layanan komunikasi VHF penerbangan saat ini, maka perlu dikembangkan sistem komunikasi VHF berbasis satelit. Penelitian ini bertujuan untuk mensimulasikan dan menganalisis komunikasi suara pada AMS(R)S frekwensi VHF (117,975 - 137 MHz) menggunakan satelit LEO sesuai dengan studi yang sedang berlangsung oleh ICAO dan ITU. Perhitungan link budget...
