Sequential Cancellation Scheme and its Performance of Multi-user Detection for W-CDMA
نویسندگان
چکیده
A sequential cancellation scheme and its improvement is given in this paper for multi-user detection. Multi-user detection is expected to enhance capacity of the Wideband CDMA scheme. This scheme is composed of (a) estimation and compensation of phase rotation using a pilot signal in multi-pass environment, and (b) iterative calculation of a target signal and its interference. This scheme has been enhanced by selecting interference components based on the output of the matched filter. Key-Words: sequential interference cancellation, wideband CDMA, multiuser detection, multipass phase rotation, pilot signal

Performance Improvement Technique for Multiple User Detection in DS-CDMA System using Groupwise Successive Interference Cancellation (GSIC)
Code Division Multiple Access (CDMA) system is being most popular communication technique due to its robustness & spread spectrum techniques. The CDMA include the pseudo sequences (PN-sequences) which provide the secure communication over a wide band. But the Multiple Access Interference (MAI) limits the capacity of Direct Sequence Code Division Multiple Access (DS-CDMA) based systems. For DS-C...

Multiuser detection by iterated soft{decision interference cancellation is known to achieve almost single user performance in low and moderate interference scenarios. In this paper, it is shown how this detection scheme can be further improved by adaptive calculation of the soft{decision rule. This enables a signiicantly higher number of active users signaling within the same bandwidth to be de...
متن کاملFrequency-Domain Multi-Stage Soft Interference Cancellation for DS-CDMA Uplink Signal Transmission
It is well-known that, in DS-CDMA downlink signal transmission, frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion can replace rake combining to achieve much improved bit error rate (BER) performance in severe frequencyselective fading channel. However, in uplink signal transmission, as each user’s signal goes through a different channel, a severe multi-user...
متن کاملAnalytical Ber Computation for Interference Cancellation
Multiple Access Interference (MAI) is a factor, which limits the capacity and performance of CDMA system. The conventional detector does not take into account the existence of MAI. Hence, a multi-user detection strategy is used for mitigating the effects of MAI. Novel receiver structures that take advantage of knowledge of MAI signal parameters are termed as Multi-user receivers and are more co...
متن کاملHYBRID INTERFERENCE CANCELLATION RECEIVER FOR DS-CDMA SYSTEMS L.Nithyanandan and P.Dananjayan
In a CDMA system, the performance of channel matched filter receivers are limited by the presence of multi-user interference. Hence receivers must be capable of suppressing these interferences. Interference suppression or interference cancellation works by subtracting the interfering users from the received signal, thus allowing an improved error rate for the user of interest. In this paper a h...
