-The following waveforms are available:
-  * [wiki:FlexWaves#DigitalModem Digital modem]
-  * [wiki:FlexWaves#UTRAN UTRAN transmitter/receiver]
-  * [wiki:FlexWaves#UTRANTDEC UTRAN Turbo encoder/decoder only]

+This waveform is a simple BPSK digital modem that uses the PC soundcard codecs to interface an speaker and a microfone. The former is used as transmitter antenna (medium is sound) whereas the latter is the receiver antenna. It contains a symbol synchronizer, preamble detector and uses turbo coding. 
 
-=== !DigitalModem ===
-
-This waveform is a simple digital modem (without channel). It can be configured to perform BPSK, QPSK, QAM4 and QAM16. The modulator/demodulator is a single program which can be instantiated as a modulator or demodulator. A binary source and a sink generate and reads random binary data.
+Before using the soundcard, we need to start the JACK server. Refer to the jack website for more information.
 
 The application can be loaded launching the following command on the runph command prompt:
+{{{
+runph$: phload modem_dac
+}}}
+
+or it can be launched without the soundcard using:
 {{{
 runph$: phload modem
 }}}
 
-The waveform can be configured using initialization parameters (at load) or using statistics (at runtime). 
-  * Initialization configuration: In the $ALOE/example-repository/statsman/modem directory, you can edit the following parameters:
-      * source.params: ''numbits'' variable selects the number of bits to generate each time slot.
-      * modulator.params: ''modulation'' variable configures the modulation: 0=BPSK, 1=QPSK, 2=QAM4, 3=PSK8, 4=QAM16
-      * demodulator.params: ''modulation'' variable must match the same variable in the modulator.params file
-      '''Note''': The rest of parameters should not be changed.
-  * Run-time Statistics configuration: 
-      * ''numbits'' variable at the source component. For instance, to generate 4096 bits, issue the following command at the runph command prompt:

+[[BR]]
 
+
+=== !ChannelAnalyzer ===
+
+This waveform is a channel analyzer. It gives the channel gain and phase for a defined interval of sequences. Bandwidth can be selected through the parameters files under statsman/channel_annalyze directory, in the annalyzer_rx.params and annalyzer_tx.params.
+
+Before using the soundcard, we need to start the JACK server. Refer to the jack website for more information.
+
+The application can be loaded launching the following command on the runph command prompt:
 {{{
-runph$: statset modem source numbits 4096
+runph$: phload channel_annalyze
 }}}
-
-And the following variables can be captured from the GUI (or reported to a file from the command prompt):
-  * Object: ''modulator'' variables: ''out_signal_i'' and ''out_signal_q'' captures the I/Q output signals
