Transmitter Pulse Shaping to Reduce OOB Power and ICI in OFDM Systems
نویسندگان
چکیده
The goal of waveform shaping techniques in orthogonal frequency division multiplexing systems is reduction in out of band (OOB) transmit power as well as reduction in inter-carrier interference (ICI) generated by carrier frequency offset at the receiver. We propose waveform shaping using a linear combination of time-limited polynomial pulses having spectral decay rates of 1=f 4 and 1=f . The resultant pulses can be optimized with respect to OOB power and bit error rate caused by ICI.

Intercarrier Interference of Various Pulse Shaping Functions Used in OFDM Systems with Carrier Frequency Offset
For orthogonal frequency-division multiplexing (OFDM) communication systems, the frequency offsets in mobile radio channels distort the orthogonality between subcarriers resulting in intercarrier interference (ICI). This paper is focused on the problem of reducing the intercarrier-interference (ICI), signal to noise ratio and improved performance in the transmission over OFDM using various puls...

متن کاملICI Reduction Through Shaped OFDM in Coded MIMO-OFDM Systems
The default pulse shaping filter in the conventional multiple-input and multiple-output (MIMO) based orthogonal frequency division multiplexing (OFDM) system is a rectangular function, which unfortunately is highly sensitive to frequency synchronization errors and the Doppler spread. Shaped OFDM is able to considerably alleviate the effect of inter-carrier interference (ICI) as well as reduce t...

This paper considers practically relevant aspects and advantages of pulse-shaping orthogonal/biorthogonal frequency division multiplexing (OFDM/BFDM) systems. We analyze the intersymbol/intercarrier interference (ISI/ICI) in such systems when they operate over time-varying channels. Two methods for an ISI/ICI-minimizing pulse design are proposed, and efficient FFT-based modulator and demodulato...
متن کاملSpectral Precoding for Out-of-Band Power Reduction Under Condition Number Constraint in OFDM-Based Systems
Due to the flexibility in spectrum shaping, orthogonal frequency division multiplexing (OFDM) is a promising technique for dynamic spectrum access. However, the out-of-band (OOB) power radiation of OFDM introduces significant interference to the adjacent users. This problem is serious in cognitive radio (CR) networks, which enables the secondary system to access the instantaneous spectrum hole....
