Frequency-Domain Pre-Rake Transmission for DSSS/TDD Mobile Communications Systems
نویسندگان
چکیده
In this Letter, a frequency-domain pre-rake transmission is presented for a direct sequence spread spectrum with time division duplex (DSSS/TDD) system under a frequency-selective fading channel. The mathematical relationship between frequency-domain and time-domain pre-rake transmissions is discussed. It is confirmed by the computer simulation that, similar to the time-domain pre-rake transmission, frequencydomain pre-rake transmission can improve the bit error rate (BER) performance. The frequency-domain pre-rake transmission shows only slight performance degradation compared to the frequency-domain rake reception for large SF. key words: frequency-domain equalization, pre-rake, spread spectrum, mobile radio

Frequency-Domain Pre-Equalization for Multicode Direct Sequence Spread Spectrum Signal Transmission
Severe frequency-selective fading, encountered in a broadband wireless mobile communication, significantly degrades the bit error rate (BER) performance of direct sequence spread spectrum (DSSS) signal transmission with rake combining. In this paper, frequency-domain pre-equalization transmission, called pre-FDE transmission, is presented for orthogonal multicode DSSS signal transmission. It is...
متن کاملOn the downlink capacity of TDD CDMA systems using a pre-Rake
The Pre-Rake technique for the downlink transmission in TDD-based CDMA wireless systems has been shown to provide greater capacity and a simpler receiver design at the mobile receiver. Nevertheless this technique is very affected by fast changing channels, since it relies on uplink channel measurements for the downlink transmission. In this paper a semi-analytical approach to the performance, i...
متن کاملPerformance Improvement in Ds-spread Spectrum Cdma Systems Using a Pre- and a Post-rake
The Rake receiver is a well known technique in spread spectrum systems, which is used to obtain signal diversity in multipath environments. In TDD systems, a technique known as pre-Rake has been proposed recently, in which the signal-processing is transferred to the transmitter, and it has been shown that this technique provides a capacity increase in the downlink. In this paper we propose a co...
متن کاملTHE SUMMARY OF Ph.D. DISSERTATION
This dissertation discusses two major topics, namely a diversity scheme and an adaptive data transmission, for realizing future broadband mobile multimedia communication systems. By using a diversity scheme and an adaptive data transmission, the system performance can be improved significantly. Since the system performances are degraded due to the inter-symbol interference (ISI) and multi-user ...
متن کاملCapacity increase in the downlink of spread spectrum systems through joint signal precoding
In this paper we propose two precoding schemes for the downlink of CDMA systems which help reduce the multiuser interference by jointly precoding the transmitted signal based on knowledge of the downlink channel. These methods provide a substantial capacity increase without requiring complex multiuser detectors at the mobile terminals and can be applied for instance to TDD systems, which have s...
