WebThe modern telecommunication age has seen the development and use of a number of schemes for sending, receiving and processing signals, namely Amplitude modulation (AM), Frequency Modulation (FM), Phase Modulation (PM), GSM, OFDM among many others. Initially telecommunication techniques were performed using analogue devices only. WebGSM used TDMA and FDMA technologies that competed with CDMA. These technologies were used to map information (bits) from multiple users into radio spectrum. In 4G, these were replaced by OFDMA, a much superior technology with better efficiency. 5G also uses OFDMA but with slight enhancements. 6 1 Kurt Behnke
