Performance analysis of a Dual Signal Receiver - TDMA/SFH system
Arjan Nollen, Gerard J. M. Janssen, Ramjee Prasad · 1996
Evaluation results of a Time Division Multiple Access (TDMA) Slow Frequency Hopping (SPH) system, using a Dual-Signal Receiver (DSR), are presented for the Rayleigh fading channel. With the DSR two narrowband Binary Phase Shift Keying (BPSK) co-channel signals can be received simultaneously. The DSR is used in the uplink to allow two users simultaneously in a frequency band, and is shown to enhance the system capacity significantly compared to a conventional receiver. In addition, antenna diversity is used in the uplink, and convolutional coding is used for uplink and downlink. Both, single and multiple-cellular systems are investigated. The performance is evaluated using simulation results in terms of average BER, capacity and spectral efficiency, using the COST 207 channel model for the macrocellular channel.
