Channel rays outside the cyclic prefix (CP) interval (also known as the "guard interval") in orthogonal frequency division modulation (OFDM) are encountered due to excessively long channels and possibly due to timing errors. This causes inter-carrier and inter-symbol interference (ICI/ISI) and hence a loss in per-subcarrier signal-to-interference and noise(More)
This work presents path loss measurements through a 20 MHz wireless channel at a carrier frequency of 3.676 GHz in a suburban setting outside Chicago, Illinois. The data collection system is described and the measurement environment is characterized. Results are presented for two seasons, winter and summer, demonstrating that tree foliage creates an average(More)
The paper describes a low-complexity technique to increase the capacity and performance of mobile broadband systems, particularly for fast changing, highly frequency selective channels. The technique is very low complexity and can be implemented with today's hardware at low cost. It entails minor scheduling constraints and pilot-plus-data aided channel(More)
