چکیده
2-dimensional (2D) block spread CDMA achieves multiple-access interference (MAI) free uplink transmission while using low-complexity single-user detection. An important problem is how efficiently to assign the limited resource of spreading codes to users. In this paper, we propose a code assignment algorithm for the uplink of a 2D block spread CDMA cellular system. It is confirmed by the computer simulation that the proposed code assignment algorithm improves the code reuse efficiency.

Combined code reuse scheme with two-dimensional OVSF codes assignment algorithm for uplink multi-user/multi-rate block spread multi-cellular CDMA
The two-dimensional (2D) block spread code division multiple access (CDMA) can avoid the uplink multiple-access interference with low-complexity single-user detection in a slow fading channel and, therefore, is very attractive. In the 2D spreading, orthogonal variable spreading factor (OVSF) is used for spreading; an important problem is how to efficiently assign the limited resource of OVSF co...

Abstract 2-dimensional (2D) block spread direct sequence-code division multiple access (DS-CDMA) allows mutli-rate without causing uplink multi-access interference (MAI) in the presence of a frequency-selective fading channel. However, in a cellular system, the inter-cell interference remains. The site selection diversity (SSD) can be used to reduce the inter-cell interference and increase the ...

Multiple-access interference (MAI) limits the bit error rate (BER) performance of CDMA uplink transmission. In this paper, we propose a generalized chip-interleaved CDMA with 2-dimensional (2D) spreading using orthogonal variable spreading factor (OVSF) codes to minimize the MAI effects and achieve the maximum available timeand frequency-domain diversity gains. We present the code assignment fo...

This paper proposes the application of M -ary orthogonal Walsh modulation for an OFDM-CDMA uplink transmission. Beside the examination of general system properties, it is shown that decision-directed phase estimation represents a channel estimation concept suitable for the new system. The Walsh modulation can also be interpreted as a linear block code with low decoding complexity, and the paper...
