A simple yet accurate analysis of the bit error rate performance for differential chaos shift keying communication system is proposed for an additive white Gaussian noise channel by using the non-central F distribution of the decision variable and assuming variable bit energy in the calculation. The new method has much higher accuracy or much lower computational complexity than the existing methods...
We propose a link adaptation technique for IEEE 802.11n MIMO-OFDM systems with convolutional coding. The technique dynamically selects the best modulation and coding scheme (MCS) based on channel conditions and on the medium access control (MAC) layer performance (coded BER or PER) requested by applications. We show that the coded performance at decoder output can be modeled as a function of decoder-input...
Satellites have played an important role in global telecommunications. However, transmission control protocol (TCP) suffers significant performance degradations over satellite links due to high bit error rate and long latency. Among methods proposed to alleviate the impact of satellite link characteristics on TCP performance, split TCP connections separated by performance enhancement proxies have...
