2x2 Stbc Mimo Ofdm Receiver Design for Wlan with Estimation of Different Transmit Carrier Frequency Offsets

چکیده
The combination of Multiple-Input Multipleoutput (MIMO) and Orthogonal Frequency Division Multiplexing (OFDM) has been viewed as the trend of the new wireless LAN technology. In this paper, the design of an up-to-date 2 x 2 Space-Time Block Coded (STBC) MIMOOFDM baseband receiver is presented with reference to an IEEE 802.11 n proposal. To solve possible different carrier frequency offsets between the two transmit antennas due to the antenna resistance match problem, this work proposes a new carrier frequency offset tracking method at the receiver. The overall design is verified on the Xilinx FPGA with an implementation loss of about 1.5 dB.

Single-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
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 synchronization has been a major problem in Cooperative Orthogonal Frequency Division Multiplexing (CO-OFDM) under the influence of both carrier frequency offset and timing offset with unknown channel gains. CO-OFDM network performance can be improved by employing Amplify-and-Forward (AF) relay strategy. The OFDM network comprises of many sub-carriers which requires an adjustment of ...
متن کاملEffect Of TO & CFO on OFDM and SIR Analysis and Interference Cancellation in MIMO - OFDM
OFDM is a multicarrier modulation technique in which a high rate bit stream is split into N parallel bit-streams of lower rate and each of these are modulated using one of N orthogonal sub-carriers. In a basic communication system, the data is modulated onto a single carrier frequency. OFDM is a promising candidate for achieving high data rates in mobile environment because of its multicarrier ...
متن کاملProposal of improved PTS method for STBC MIMO-OFDM in the non-linear channel
Partial Transmit Sequences (PTS) seems to be attractive for Peak to Average Power Ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) system, since it obtains better PAPR property by modifying OFDM signals without distortion. Meanwhile it also shows the potential to be utilized in STBC MIMO-OFDM system. The PTS method can reduce the PAPR by controlling the multiplied wei...
