Abstract :
In personal communications systems, users contend for the resources of frequency and time, with re-use determined by spatial separation, power allocation, antenna beam patterns, data rate, and the required signal to interference ratio for reliable operation. We describe a highly adaptive system with distributed control, i.e., each link is optimized independently, with coupling only via the mutual interference. It will include frequency hopping, variable bit and power allocation, channel coding, adaptive equalization, coherent M-QAM signaling, rapid channel probing, and adaptive transmitter and receiver antenna arrays
