OFDM Blocks

Collaboration diagram for OFDM Blocks:

Classes
class	gr::digital::ofdm_carrier_allocator_cvc
	Create frequency domain OFDM symbols from complex values, add pilots. More...
class	gr::digital::ofdm_chanest_vcvc
	Estimate channel and coarse frequency offset for OFDM from preamblesInput: OFDM symbols (in frequency domain). The first one (or two) symbols are expected to be synchronisation symbols, which are used to estimate the coarse freq offset and the initial equalizer taps (these symbols are removed from the stream). The following n_data_symbols are passed through unmodified (the actual equalisation must be done elsewhere). Output: The data symbols, without the synchronisation symbols. The first data symbol passed through has two tags: 'ofdm_sync_carr_offset' (integer), the coarse frequency offset as number of carriers, and 'ofdm_sync_eq_taps' (complex vector). Any tags attached to the synchronisation symbols are attached to the first data symbol. All other tags are propagated as expected. More...
class	gr::digital::ofdm_cyclic_prefixer
	Adds a cyclic prefix and performs pulse shaping on OFDM symbols. More...
class	gr::digital::ofdm_frame_acquisition
	take a vector of complex constellation points in from an FFT and performs a correlation and equalization. More...
class	gr::digital::ofdm_frame_equalizer_vcvc
	OFDM frame equalizer. More...
class	gr::digital::ofdm_frame_sink
	Takes an OFDM symbol in, demaps it into bits of 0's and 1's, packs them into packets, and sends to to a message queue sink. More...
class	gr::digital::ofdm_insert_preamble
	insert "pre-modulated" preamble symbols before each payload. More...
class	gr::digital::ofdm_mapper_bcv
	take a stream of bytes in and map to a vector of complex constellation points suitable for IFFT input to be used in an ofdm modulator. More...
class	gr::digital::ofdm_sampler
	does the rest of the OFDM stuff More...
class	gr::digital::ofdm_serializer_vcc
	Serializes complex modulations symbols from OFDM sub-carriers. More...
class	gr::digital::ofdm_sync_sc_cfb
	Schmidl & Cox synchronisation for OFDM. More...
class	gr::digital::packet_header_ofdm
	Header utility for OFDM signals. More...
