Performance analysis of a dual signal receiver-TDMA/SFH system in a macro-cellular environment
Arjan Nollen, Gijs Jansen, Ramjee Prasad · 2002
Evaluation results of a time division multiple access (TDMA) slow frequency hopping (SFH) system, using a dual signal receiver (DSR), are presented for the Rayleigh fading channel. With the DSR two narrow band 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 the uplink and downlink. Both, single and multiple-cellular systems are investigated. The performance is evaluated using simulation results in terms of the average BER, capacity and spectral efficiency, using the COST 207 channel model for the macro-cellular channel.
