The effect of jitter noise on binary input intersymbol interference channel capacity
نویسندگان
چکیده
The effect of signal dependent jitter noise on channel capacity is investigated. Upper and lower bounds on capacity are computed numerically for channels with a mix of signal dependent jitter noise and additive white Gaussian noise. The resulting bounds allow for comparison of potential coding gain for differing amounts of jitter noise and varying code rates. The comparison provides insight into the effect jitter noise has on channel capacity and shows that in some cases there is significantly more coding gain possible when the noise is predominantly jitter noise.

Gaussian Z Channel with Intersymbol Interference
In this paper, we derive a capacity inner bound for a synchronous Gaussian Z channel with intersymbol interference (ISI) under input power constraints. This is done by converting the original channel model into an n-block memoryless circular Gaussian Z channel (n-CGZC) and successively decomposing the n-block memoryless channel into a series of independent parallel channels in the frequency dom...
متن کاملCapacity Bounds and High-SNR Capacity of the Additive Exponential Noise Channel With Additive Exponential Interference
Communication in the presence of a priori known interference at the encoder has gained great interest because of its many practical applications. In this paper, additive exponential noise channel with additive exponential interference (AENC-AEI) known non-causally at the transmitter is introduced as a new variant of such communication scenarios. First, it is shown that the additive Gaussian ch...
متن کاملOn the low-rate Shannon limit for binary intersymbol interference channels
For a discrete-time, binary-input Gaussian channel with finite intersymbol interference (ISI), we prove that reliable communication can be achieved if and only if Eb=N0 > log 2=Gopt, for some constant Gopt that depends on the channel. To determine this constant, we consider the finite-state machine which represents the output sequences of the channel filter when driven by binary inputs. We then...
متن کاملModulation and Coding for Linear Gaussian Channels - Information Theory, IEEE Transactions on
Shannon’s determination of the capacity of the linear Gaussian channel has posed a magnificent challenge to succeeding generations of researchers. This paper surveys how this challenge has been met during the past half century. Orthogonal minimumbandwidth modulation techniques and channel capacity are discussed. Binary coding techniques for low-signal-to-noise ratio (SNR) channels and nonbinary...
متن کاملMultipath fading effects on carrier recovery of BPSK signal in digital radio - Communications, Speech and Vision, IEE Proceedings I
Tracking performance of the I-Q carrier recovery loop for BPSK signal in bandlimited channel with multipath interference is analysed. The multipath fading channel is characterised by the Rummler’s model (a simplified three-ray model) for line-of-sight digital radio system. A closed-form expression for the phaseerror variance related to the multipath interference, intersymbol interference and ch...
