Subject: Block Modifications: digital.mpsk_receiver_cc: Set reasonable
default parameter values for GRC definition digital.ofdm_insert_preamble:
Expose enter_preamble() as public, to allow external state changes
Cleanup of incorrect forecast behavior
Make the flag port optional, incase external preamble triggers
are preferred to in-band gr_vector_source: added set_data( data ) and
rewind() public methods gr_head: added set_length(int) method to modify head
length
New Blocks Added:
gr_keep_m_in_n: Allows periodic extraction of M items instead of 1 (in keep_1_in_n)
gr_pack_k_bits: Complementary block fo gr_unpack_k_bits
gr_vector_insert_x: Complement to the gr_head block, inserts a vector into a stream then becomes a pass through
