The bit error rate analysis obtained in this paper facilitates predicting the performance of various space-frequency pre-filtering schemes without massive simulations.Abstract:
We analyze the performance of joint space-frequency pre-filtering and equalization techniques for downlink multi-carrier code division multiple access in terms of average bit error rate performance. Several linear power allocation strategies combined with single-user equalization schemes are compared with a joint pre-filtering with an equal power constraint at the base station and maximal ratio combining at the mobile terminals. Our bit error rate analysis obtained in this paper facilitates predicting the performance of various space-frequency pre-filtering schemes without massive simulations.

Transmitter precoding in synchronous multiuser communications
Branimir R. Vojcic,Won Mee Jang +1 more
TL;DR: A synchronous multiuser system operating in an additive white Gaussian noise channel, with or without multipath fading, is considered and it is shown that both multiple access and intersymbol interference can be eliminated by means of a suitable transmitter precoding scheme.

Transmitter-based multiuser interference rejection for the down-link of a wireless CDMA system in a multipath environment
TL;DR: Two methods are introduced that are able to combat both degradations, yet allow the receiver to remain as simple as a single user receiver for a perfect channel in wireless code division multiple access communications systems.
