Modulation adaptation according to radio channel pulse response
In this paper the method for radio channel pulse response processing and modulation adaptation principle is described. The received signal is converted by baseband conversion, digitized and the pulse response of radio channel is processing by proposed algorithms. These algorithms are working in real time and are able to estimate the amplitude, phase and delay of the received signal in each of propagation paths. The most promising algorithm (Exponential Power Descend Algorithm) achieved recovery successfulness of all signal paths equal approximately 90 % for SNR = 2.5 dB. The advisable modulation is calculated from pulse response of radio channel and is immediately used in actual radio channel.
