  • On the performance of sequences for uplink QS-CDMA system [articol] 
    Khan, Zaheer; Halunga, Simona (Timişoara:Editura Politehnica, 2008)
    Loosely Synchronized (LS) sequences having Interference Free Window (IFW) are considered to be good candidates for QS-CDMA systems. The recent LS sequence constructions have generated very small sets of sequences exhibiting ...
  • Performance increase in multiuser detection systems using convolutional encoding [articol] 
    Halunga, Simona; Marcu, Ioana; Fratu, Octavian (Timişoara:Editura Politehnica, 2008)
    The paper aims to present the usage of turbo codes in multiuser detection systems. The result for bit error rate is shown here and they are obtained from Matlab simulation. Results for multiuser conventional detector, ...
