function	error_counter_v7c (in RECEIVED_DATA, in REFERENCE_DATA, in param)

Detailed Description

General error counter.

Generic error counter. Takes any received sequence, any reference data, and counts errors. The data is partitioned into blocks of variable length, and each block is synchronized, mapped, and counted independently. It is not optimized for any case in particular, and faster algorithms may be available. See BERT_v1 for other options and usage example.

Parameters

RECEIVED_DATA	received data, normalized to unity power
REFERENCE_DATA	reference data. For constellation orders >=2, if this is type logical, counter constructs symbols assuming binary delay & add. If this is type uint16, counter assumes they are symbols.
param.L	Counter block length, set to inf for one block (required)
param.M	Constellation order (required)
param.const_type	Constellation type (default QAM, see const_ref.m for options)
param.coding	coding type (required) {'gray' | 'bin'}
param.decision_type	decision type (default hard) {'hard' | 'soft'}
param.ber_th	BER threshold (throw away blocks with worse BERs than this) (default 0.1)

Return values

ber	bit error rate of full sequence
ser	symbol error rate of full sequence
ber_block	bit error rate per block (array)
ser_block	symbol error rate per block (array)
blockmap	logical array of blocks with ber<param.ber_th
err_bits	number of bit errors
totalbits	number of bits counted
err_symb	number of symbol errors
totalsymb	number of symbols counted
ORIG_SYMBOLS	symbol sequence used for counting (optional)
RX_SYMBOLS	symbol sequence counted (optional)
