在层次结构块中使用gr::fec::code::cc_encoder类

我已经实现了一个非常基本的C++CCSDS卷积编码器(k = 7，r = 1/2)，它工作得很好。然而，它是非常基本的，并且缺乏操作模式(CC_STREAMING、CC_TERMINATED、CC_TAILBITING、CC_TRUNCATED)等选项。。等

因此，我决定使用默认的gnuradio gr:：fec:：code:：cc_encoder类。我的编码超类将包括打孔和其他块，因此所有内容都将在一个层次块中。到目前为止，我将把这些块一个接一个地放在以gr:：fec:：code:：cc_encoder开头的分层块中。下面是我的.cc实现文件。

#ifdef HAVE_CONFIG_H
#include "config.h"
#endif
#include <gnuradio/io_signature.h>
#include "debug_conv_encoder_impl.h"
namespace gr {
namespace baseband {
debug_conv_encoder::sptr
debug_conv_encoder::make(int frame_size, std::vector<int> polys, int mode, int pad)
{
return gnuradio::get_initial_sptr
(new debug_conv_encoder_impl(frame_size, polys, mode, pad));
}
/*
* The private constructor
*/
debug_conv_encoder_impl::debug_conv_encoder_impl(int frame_size, std::vector<int> polys, int mode, int pad)
: gr::hier_block2("debug_conv_encoder",
gr::io_signature::make(1, 1, sizeof(unsigned char)),
gr::io_signature::make(1, 1, sizeof(unsigned char)))
{
//Creating convolutional encoder
int k = 7;
int rate = 2;
bool d_pad = (pad == 1) ? true : false;
cc_mode_t d_mode = get_mode(mode);
gr::fec::code::cc_encoder::sptr encoder(gr::fec::code::cc_encoder::make(frame_size,k,rate,polys,0,d_mode,d_pad));
//connect(self(),0,self(),0); -- Works fine
connect(self() , 0 , encoder , 0); // --gives an error
connect(encoder , 0 , self() , 0); // --gives an error
//connect(encoder);
}
cc_mode_t debug_conv_encoder_impl::get_mode(int mode)
{
switch(mode)
{
case 0:
return CC_STREAMING;
case 1:
return CC_TERMINATED;
case 2:
return CC_TRUNCATED;
case 3:
return CC_TAILBITING;
default:
return CC_STREAMING;
}
}
/*
* Our virtual destructor.
*/
debug_conv_encoder_impl::~debug_conv_encoder_impl()
{
}

} /* namespace baseband */
} /* namespace gr */

这是头文件

#ifndef INCLUDED_BASEBAND_DEBUG_CONV_ENCODER_IMPL_H
#define INCLUDED_BASEBAND_DEBUG_CONV_ENCODER_IMPL_H
#include <baseband/debug_conv_encoder.h>
#include <gnuradio/fec/cc_encoder.h>
namespace gr {
namespace baseband {
class debug_conv_encoder_impl : public debug_conv_encoder
{
private:
cc_mode_t get_mode(int mode);
public:
debug_conv_encoder_impl(int frame_size, std::vector<int> polys, int mode, int pad);
~debug_conv_encoder_impl();
// Where all the action really happens
};
} // namespace baseband
} // namespace gr
#endif /* INCLUDED_BASEBAND_DEBUG_CONV_ENCODER_IMPL_H */

不幸的是，编译和链接文件(cmake..&&make)会出现以下错误：

xxx/GRC/baseband/gr-baseband/lib/debug_conv_encoder_impl.cc:53:39: error: no matching function for call to ‘gr::baseband::debug_conv_encoder_impl::connect(gr::hier_block2::opaque_self, int, gr::fec::generic_encoder::sptr&, int)’
connect(self() , 0 , encoder , 0);
/usr/local/include/gnuradio/hier_block2.h:105:10: note:   no known conversion for argument 3 from ‘gr::fec::generic_encoder::sptr {aka boost::shared_ptr<gr::fec::generic_encoder>}’ to ‘gr::basic_block_sptr {aka boost::shared_ptr<gr::basic_block>}’

基本上；gr:：fec:：generic_encoder:：sptr｛aka boost:：shared_ptr<gr:：ffe:：genetic_encoder>｝'到'gr:：basic_block_sptr｛；意味着共享指针gr:：fec:：generic_encoder不能按照hier_block2.connect(basic_block_sptr src，int src_port，basic_blocks_sptr dst，int dst_port)的要求转换为gr:：basic_block。

我已经用这种方式创建了许多分层块，但从未遇到过这个错误。我很确定我错过了什么大事。如有任何帮助，我们将不胜感激。顺便说一句，如果需要更多信息，请告诉我。干杯
