Power line noise is significantly affects on the bit error rate performance of broadband power line communications. The channel model is affected by stochastic attenuation and deep notches which can lead to the limitation of the channel capacity and achievable data rate. In this paper, we analyze the bit error rate (BER) of orthogonal frequency division multiplex (OFDM) using binary phase shift keying...
Multicarrier code division multiple access (MC-CDMA) is a technique that combines orthogonal frequency division multiplexing (OFDM) and CDMA. The performance analysis of MC-CDMA system with correlated fading channels with α-μ distribution is investigated in this paper. We employ the binary phase shift keying (BPSK) modulation scheme and the maximal ratio combing (MRC) technique at the receiver. By...
In an orthogonal frequency division multiplexing (OFDM) system, the cyclic prefix (CP) is added to the beginning of each symbol to prevent intersymbol interference (ISI) and intercarrier interference (ICI). In practical OFDM system, the CP lengths are fixed. When the CP length is shorter than the channel impulse response (CIR) length, referred to as "insufficient CP", significant signal...
Multiple Input Multiple Output (MIMO) systems have been extensively studied in context of wireless communication systems, which promising the both increased capacity and link level reliability. In this paper, we proposed the interference cancellation techniques for V-BLAST/STBC architecture, which integrates Alamouti space-time block code (STBC) layer together with vertical Bell-laboratories (V-BLAST)...
In this paper, we present the performance analysis of multi-hop decode-and-forward (DF) cooperative communications under Rayleigh fading channel. The source, multiple relays and destination nodes are equipped with single antenna transceiver while the transmission channels are assumed to be mutually independent. A time-division channel allocation scheme is occupied in order to realize orthogonal channelization,...
This paper presents an analysis of cooperative direct-sequence code division multiple access (DS-CDMA) relay communications with one source terminal and two relay nodes with multiuser detection over the frequency-flat fading channel for uplink transmission where the decode-and-forward (DF) protocol is employed at the relay nodes. We analyze for synchronous transmission with binary phase shift keying...
