The most commonly used algorithm is the LMS algorithm, but other algorithms like Recursive Least Squares (RLS) or Normalized Least Mean Square (NLMS) can also be employed. Coefficient Update: Update the coefficients of the adaptive equalizer using an adaptation algorithm. The error is typically computed using a metric such as mean square error (MSE) or least mean square (LMS) error.Ħ. Error Calculation: Compare the output of the equalizer with the known transmitted symbols from the training sequence to calculate the error. The equalizer will process the received signal using its current coefficients and produce an output estimate.ĥ. Equalizer Output: Apply the received signal samples to the adaptive equalizer. Sample the received signal at the symbol rate to obtain discrete-time samples.Ĥ. Receive and Sample: Receive the transmitted training sequence at the receiver end of the channel. The training sequence should be designed to have properties that allow for easy estimation of channel characteristics, such as known symbols or specific patterns.ģ. Transmit Training Sequence: Transmit a known training sequence through the channel. This can be done randomly or with predefined values.Ģ. Initialization: Initialize the coefficients of the adaptive equalizer. Here's a general outline of the training sequence process with an adaptive equalizer:ġ. The purpose of adaptive equalization is to mitigate the effects of channel distortion, such as intersymbol interference (ISI), by adjusting the equalizer coefficients based on the received signal. Adaptive equalization is commonly used in applications such as wireless communication systems, digital audio processing, and equalization of data transmission channels. Any tips to help them get started? #newhire #welcomeĪpplying a training a sequence with an adaptive equalizer for signal processing typically involves a process known as adaptive filtering.
