Subband Adaptive Array for DS-CDMA Mobile Radio
We propose a novel scheme of subband adaptive array (SBAA) for direct-sequence code division multiple access (DS-CDMA). The scheme exploits the spreading code and pilot signal as the reference signal to estimate the propagation channel. Moreover, instead of combining the array outputs at each output tap using a synthesis filter and then despreading them, we despread directly the array outputs a...
متن کاملSubband Adaptive Array for MIMO-STBC CDMA System
This paper presents interference suppression using a subband adaptive array (SBAA) for uplink space-time block coding (STBC) code division multiple access (CDMA) under a frequency selective fading (FSF) channel. The proposed scheme utilizes CDMA with STBC and a receive array antenna with SBAA processing at the receiver. The received signal is converted into the frequency domain before despreadi...
متن کاملDownlink beamforming for DS-CDMA mobile radio with multimedia services
Downlink beamforming is a promising technique €or DS-CDMA systems with multimedia services to eflectively reduce strong interferences induced by high data rate users. In this paper, we first proposed a new downlink beamforming algorithm which converts downlink beamforming problem to a virtual uplink one and takes into account of the data rate information of all users. Since the main complexity ...
متن کاملMc/ds-cdma versus Sc/ds-cdma in Mobile Radio: Spectral Efficiency Approach
The spectral efficiency of a multicarrier direct-sequence code-division multiple-access (MC/DS-CDMA) cellular system operating in a mobile radio environment with Rayleigh fading, is investigated. In this work, spectral efficiency is evaluated in terms of channel capacity (in the Shannon sense) per user, estimated in an average sense. It is analytically shown that, under normalized conditions an...
متن کاملInnovative chip waveforms in microcellular DS/CDMA packet mobile radio
The impact of innovative chip waveforms on the performance of a direct sequence code-division multiple-access (DSICDMA) packet mobile radio network is investigated, assuming either Rayleigh or Nakagami-m frequency selective channels and a differential phase shift keying (DPSK) receiver with selection diversity. A constant improvement of the bit-error rate (BER) and the throughput is presented t...
