Variable rate multitone system for multipath fading channels
نویسندگان
چکیده
A continuous adaptive modulation multitone system for multipath fading channels is shown. To obtain a target BER and maximum aggregated rate, each subcarrier bit rate is modified independently to adjust the transmitted signal to the spectral channel shape and to track the channel variations dynamically. Spectral efficiency and the required feedback channel capacity are obtained through simulation over a multipath Rician channel.

A Unified Approach to the Analysis of Multicarrier DS-CDMA over Nakagami-m Fading Channels
A class of unified multicarrier DS-CDMA (MC DS-CDMA) schemes is defined and its performance is considered over multipath Nakagamim fading channels. The spacing between two adjacent subcarriers of the unified MC DS-CDMA scheme is a variable, allowing us to gain insight into the effects of the spacing on the bit error rate (BER) performance of MC DS-CDMA systems. This unified MC DS-CDMA scheme in...

متن کاملEffect of fading, diversity and interference on the performance of multitone CDMA systems
The performance of a multitone Code Division Multiple Access (CDMA) system is investigated in this paper by considering the effect of multipath fading, diversity and narrowband interference. The performance is evaluated in terms of the average bit error rate when both multiple access and partial band interference are present. Results are obtained by deriving the statistics of the receiver outpu...
