摘要: In an example embodiment, a method of adjusting a modulation and coding scheme may include selecting a modulation and coding scheme for multiple terminals and broadcasting a modulation and coding scheme identifier to the terminals. The modulation and coding scheme identifier may be configured to identify the selected modulation and coding scheme such that each of the plurality of terminals transmits a transmission to the base station based at least in part on the selected modulation and coding scheme.

摘要: A digital receiver system to recover signals from inter-symbol-interference includes a finite impulse response (FIR) filter using convolution to recover signals; and a channel estimator coupled to the FIR filter to estimate FIR coefficients, wherein the channel estimator uses a second order expectation and a fourth order expectation from a convolution to calculate error function.
