BER Performance Comparison of Overlap FDE and Sliding-window Time-domain Equalization for Single-carrier Transmission
نویسندگان
چکیده
Minimum mean square error frequency-domain equalization (MMSE-FDE) can achieve a good performance in the case of single-carrier (SC) transmission in a frequencyselective fading channel. The conventional FDE requires the insertion of guard interval (GI) to avoid the inter-block interference (IBI). However, the GI insertion reduces the throughput. Recently, overlap FDE which requires no GI insertion was proposed. Another promising equalization technique which requires no GI insertion is sliding-window timedomain equalization (SWTDE). In this paper, we compare overlap FDE and SWTDE in terms of the bit error rate (BER) performance and computational complexity for single-carrier transmission.

متن کاملSystematic design of single carrier overlap frequency domain equalization
This paper proposes a systematic design method of overlap frequency domain equalization (FDE) for single carrier (SC) transmission without a guard interval (GI). Based on the analysis of signal-tointerference-plus-noise ratio (SINR) of the equalizer output for each symbol, we adaptively determine the block of the overlap FDE, where the block is defined as a set of symbols at the equalizer outpu...

In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Orthogonal frequency division multiplexing (OFDM) is a suitable candidate for broadband power line communications (PLC). It has shown that the Bit Error Rate (BER) performance of Single Carrier Transmission with Frequency Domain Equalization (SCT-FDE) is close to OFDM in broadband wireless systems.

متن کاملOversampling Frequency-domain Equalization for Single-carrier Transmission in the Presence of Timing offset
Frequency-domain equalization (FDE) based on minimum mean square error (MMSE) criterion is a promising equalization technique for the broadband single-carrier (SC) transmission. However, the presence of timing offset produces the inter-symbol interference (ISI) and degrades the bit error rate (BER) performance. In this paper, we discuss the mechanism of the BER performance degradation in the pr...
