Sentence examples for complex equalization from inspiring English sources
Thus, the OM-OFDM method still maintains the ease of equalization, whereas the CE-OFDM method requires a more complex equalization process.
Moreover, NB-LDPC-coded modulation exhibits lower receiver latency than binary LDPC-coded modulation, especially when complex equalization schemes are employed [17].
In OFDM, high-rate data streams can be broken down into a number of parallel lower-rate streams, thereby avoiding the need for complex equalization.
The wireless channel is thus prone to inter-symbol interference (ISI) which severely degrades the system performance and requires complex equalization techniques at the receiver.
While most contributions in literature consider only the frequency flat case, this paper shows how MIMO orthogonal frequency division multiplexing systems and MIMO single-carrier systems can be deployed by simple low complex equalization techniques.
In other application areas, such as aero- and underwater acoustics, the relative bandwidths of signals may occur to be so large as to enforce the use of complex equalization techniques in conjunction with super-directive arrays [17, 23].
It is then easy to implement low complexity equalization at the receiver by using a set of complex multipliers, one for each sub-band, provided the channel state information is available[4].
However, this high bit rate transmission is susceptible to channel frequency selectively and requires complex channel equalization at the receiver to recover from the resulting intersymbol interference.
Albeit, the return link in consumer applications is usually large making equalization complex.
Two alternative low-complexity linear equalizer structures with MSE criterion are considered for subband-wise equalization: a complex FIR filter structure and a cascade of a linear-phase FIR filter and an allpass filter.
This way, computationally complex intersymbol interference (ISI) equalization is avoided and channel estimation/equalization task becomes easier.
